These days, everyone who's anyone is partying over in the Twitterverse (bonus -- you don't even have to leave your couch!), and celebs are no exception. Also, if you don't know what Twitter is, a.) Seriously?!, and b.) Watch this.

Anyway, we here at Buzzworthy love Twitter because, well, we Tweet! But also, we love Twitter because the sheer entertainment value of following your favorite celeb CANNOT be overlooked. We've laughed, we've cried, we've poked our eyes out (after reading John Mayer's penis-falling-asleep Tweet) and attempted to set our keyboards on fire (ENERGY!). But we always come back for more.

So, herewith is our roundup of our favorite, must-follow celebrities who Twitter.

CLASS A CRAZIES: This group includes the "must-follows" -- the celebrities whose Tweets are so friggin' BANOODLES you simply cannot miss them.
+ Diddy (@iamdiddy) -- If you follow NO ONE else on this list, please, please, please follow Diddy. (LET'S GO, PEOPLE!)
+ MC Hammer (@MCHammer) -- Apparently he was hiding an early adopter in those glittery Hammer pants!
+ Shaqille O'Neill (@THE_REAL_SHAQ) -- Shaq lives in Twitteronia.
+ Snoop Dogg (@snoopdogg) -- His "izzle" talk just slays me every time. Occassionally Tweets while toking.
+ Steve Buscemi (@steve_buscemi) -- He hates penguins!
+ Solange Knowles (@solangeknowles) -- Love Solange, but when is she NOT Twittering. I think she's the sole reason Twitter keeps crashing.
+ Xzibit (@mrxtothaz)
+ Ryan Seacrest (@RyanSeacrest) -- Dude Tweets DURING COMMERCIAL BREAKS of American Idol! HOW IS THAT EVEN ALLOWED?
+ Lily Allen (@lilyroseallen) -- Lily still kinda hates Perez Hilton, and they are FOREVER back-and-forthing forever on Twitter.
+ Heidi Montag (@montagheidi) -- I swear to the Lord, you will S--T when you see how many of Heidi's Tweets are about Jesus!
+ Spencer Pratt (@prattspencer) -- Sometimes he's on the Bible train too, and he once even compared himself to Jesus. Epic.

FAMOUS BUT KINDA BORING: This group is dependable though almost never shocking. But they're all famous, so they've usually got somewhat interesting things to say. Just don't expect ALL CAPS Diddy rants or Lily Allen vs. Perez Hilton feuds):
+ Britney Spears (@britneyspears) -- Sometimes Britney's team posts for her, but this is still a good one.
+ Selena Gomez (@selenagomez) -- Yay, Selena!
+ Demi Lovato (@ddlovato) -- Demi and Selena leave each other little Twitter notes. 'Scute!
+ Taylor Swift (@taylorswift13) -- W00t Taylor! Predictably, Taylor Swift's Tweets are sweet.
+ Dave Matthews (@davejmatthews)
+ Soulja Boy Tell 'Em (@souljaboytellem) -- Mostly Soulja wants you to click on shiz for him and make him more famous. Soulja Boy also Tweets his beef with 50 Cent. (That was one of the weirdest sentences I've ever typed.)
+ Dave Navarro (@davenavarro6767) -- Tweets about being bored and playing video games. Fair enough, we say!
+ John Mayer (@johncmayer) -- He's become a bit of a mad Twitterer lately, and I'm actually a little tempted to move him to the above category. He once Tweeted about his penis falling asleep.
+ Sara Bareilles (@SaraBareilles) -- Sara Bareilles really needs to Twitter more.
+ Mark Hoppus (@markhoppus) -- He's been Tweeting about blink's new album a lot.
+ A Cursive Memory (@acursivememory) -- They really need to Tweet more.
+ Simon Curtis (@simoncurtis) -- Yay! We LOVE Simon Curtis! Posts fun pix of his trips.
+ Regina Spektor (@reginaspektor)

+ LeAnn Rimes (@leannrimes)
+ DJ AM (@DJ_AM)
+ REM (@remhq)
+ Duran Duran (@duranduran) -- Yes, they ARE still around!
+ Nick Cannon (@nickcannon4real) -- Mr. Mariah Carey is livin' large in the Twitterverse too.
+ William Beckett (@billbeckett)

+ Four Year Strong (@fys)
+ Janelle Monae (@janellemonae)
+ Katy Perry (@katyperry) -- More exciting IRL than on Twitter. Oh wells.

+ Cinema Bizarre (@cinemabizarre) -- Lady Gaga's German tourmates are also Twittering!

More celebrities on Twitter after the jump!

For our latest installment of "Buzzworthy Twitters With," let's say twhello (AH-GAIN) to Diddy! Yes, we know that we just Twittered with Diddy, but this stuff is waaaay too good to ignore. Also, Diddy has changed his name yet again and would now like to be referred to as P Twitty.

Diddy's Tweets are in bold (and, increasingly, ALL CAPS), and our responses are in italics. We'd also like you to note that the timestamps for most of these are verrrry late at night. OK, buckle up because it's gonna be a srsly bumpy ride!

I love yall!!! I want to dedicate this to yall: http://tiny.cc/VgIF1 !!!!!   1:02 AM Mar 15th from web
Awww... we love you too, Diddy! Sneaking in a Beatles song like that was so sweet!

Fyi I'm not drunk or high this is just how I feel rt now!!! So let's go!!! lol   1:14 AM Mar 15th from TwitterBerry
Uh, we didn't think you were drunk or high. But, uhm, not to push the issue or anything, but sometimes when people ARE high they get paranoid. And you seem kinda paranoid right now. But whatevs. If you SAY you're not high, then we t-o-t-a-l-l-y believe you. Diddy is DEFINITELY NOT HIGH.

Life is what you make it!!!! Don't stop!!!   1:30 AM Mar 15th from TwitterBerry
Hells yeah! (And also: Don't stop what???)

Thanks for the Support and Love Energy People!!! HIT @jayelectronica with more electricity directly to his cell!!!! 1-504-377-5928 LETS GO!!   3:00 AM Mar 15th from web
What if @jayelectronica (rapper/ producer/ Erykah Badu's dude) wasn't up for all 195,000+ Diddy followers hittin' him up on his cell like that... even for the promise of "more electricity."

Can you feel it?!?! I can feel it!!! If you wanna feel it click here: http://tinyurl.com/2n8fz5 !!!!!!   3:44 AM Mar 15th from web

YALL TIRED YET???????   about 15 hours ago from TweetDeck
Um, quite frankly, I don't think I've ever been this tired in my life.

Well, that was exhausting. I almost wish Diddy would go back to having tantric sex like last week...

See you round the Twitterverse!

+ It was pretty much all Lindsay Lohan ALL THE TIME this weekend. We could barely keep up with all the mayhem! Let's see: a warrant was issued for Lindsay's arrest. After which, she was secret Twittering. She and Samantha Ronson were fighting. And, uhm... it was kinda total freaking chaos. And, it turns out, maybe the whole thing was a misunderstanding? Huh? (MTV News)

+ Know what amazes the crap out of me? Despite ALL the shiz that's gone down with Michael Jackson, the dude can STILL sell out concerts like nobody's bizness. We are a forgiving people. (Evil Beet)

+ Uh, apparently British comedian/ persona non grata #1 amongst Jonas Brothers fans Russell Brand hasn't had a chance to read our round-up of Miley Cyrus' new book Miles To Go. Cause he doesn't get why a 16-year-old is writing a memoir... and also he kinda told her to STFU. (Ace Showbiz)

+ Jonas Brothers were in the Bahamas this weekend. I wanna job where I can work from the Bahamas. (JonasHQ)

+ Lady Gaga brought some of her special brand of GAH to Flight of The Conchords this weekend. It was GAH-tastic? (We guess? We don't have HBO anymorez. Grrrr, recession!). (Evil Beet)

+ We did, however, catch Kelly Clarkson, who brought down the house on Saturday Night Live this weekend. She performed "My Life Would Suck Without You" and "I Do Not Hook Up," from her hit album All I Ever Wanted, and we likey-d a LOHT. (Pop Crunch)

+ Selena Gomez looks pretty damn drop-dead gorge on the cover of Latina mag, doncha think? (Just Jared)

+ HOLY CRAP! For once we agree with Gwyneth Paltrow: she thinks this whole Joaquin Phoenix becoming a rapper thing is a crock of GOOP. (MTV News)

To anyone who thinks 16 is too young to be writing your life memoirs, Miley Cyrus says: EFF OFF!

WE KID!

Miley, of course, didn't say that at all. In fact, Miley totally gets that she has way more of her life to live, more hit songs to write, loads more boys to date, and maybe even another scandal or five.

That's why she called her new memoir Miles To Go. GET IT??? (She's got miles to go in her own life people. Sheesh, do we have to do e-v-e-r-y-t-h-i-n-g around here??).

Anyway.

Here are the top 5 things you really need to know about Miley's new autobiography, lest you MORTIFY yourself by revealing you DIDN'T know that...

5. Miley has tachycardia: Don't be embarrassed... we had to look it up too. It's a heart condition that causes her heart rate to speed up. But not to worry! Miley is totally fine and she said it won't kill her (phew!). Just try not to make any sudden movements around her... or loud noises.

4. Miley's relationship with her dad is NOT weird: We covered this one already, but it does bear repeating. Miley + Billy Ray have a totally normal relationship.

3. Miley has been bullied: In case you're wondering who in their right mind would get into a schoolyard brawl with Miley, the book is packed with references to mean girls. (Rudeness!) We're guessing those girls feel pretty stupid these days, if not completely less successful and lame.

2. Nick Jonas: Yes people. There IS some Jonas Brothers dirt in the book. Miley discusses her romance with Nick and even refers to him as "Prince Charming" and goes into more detail about "7 Things" and how she was gonna be all like "I'm not gonna write you a love song" but she's not a hater. Swoon!

1.Miley HAS been spanked:Get your minds out of the gutter! She means by her parents.

Needless to say, we're already looking forward to Miley's next book, Mile High Club? (Again... kidding!)

Look, we love Radiohead as much as the guy in the dorm room next to you, and, like every other sentient being on this planet, we'll be in line for those Radiohead collectors editions of Pablo Honey, The Bends, and OK Computer out March 24, and all of the new/old Radiohead vinyl out April 21. But Radiohead's prolific musical genius aside, dudes are beefin' harder than McDonald's!

Apparently, for these indie rock gods, the answer to the age-old question "Can't we all just get along?" is "Bloody hell, no!" Who knew these twee Brits had so many issues to work through!?

Therefore, here are the top 5 folks Radiohead basically hates.

5. Miley Cyrus: Apparently Miley was hoping to get just a few short mins of Radiohead's (i.e. her FAVE BAND's) time at the Grammys this year. Radiohead's response: "Uh... we don't really do that." HEISMANED!

4. Kanye West: Is also none too pleased with Thom Yorke Ltd. Apparently Kanye was also looking to get a little Grammy facetime with Radiohead. Unfortunately, 'Ye didn't get the Miley memo and felt snubbed (I know! Shocking, right?) when Radiohead basically ignored him. But Kanye SO got them back!!! When they performed he "sat the f*** down." OOH! BURN!

3. The Hold Steady: Tad Kubler, guitarist for Brooklyn rock darlings The Hold Steady, said some not-so-nice things about Thom Yorke, and guess what? BOOM! Tad ends up in the hospital with a busted pancreas. You do the math.

2. The Pixies: Thom claims this one was total "rubbish," but he was kind of caught freaking out that Radiohead was performing after the Pixies at Bonnaroo back in '06. Thom says that what he REALLY meant was that the Pixies should be headlining above them. Right... Ok. Zzzz.

1. Oasis: Oasis' Liam Gallagher has, by far, proven himself to be Yorke's most worthy opponent. These two have a love/hate relationship that goes way back, and these guys are not afraid to get down-and-dirty personal. In fact Gallagher said of Radiohead fans: "they are boring... and ugly." Funny! I've always thought the same thing of the Gallagher brothers!

Our advice: Just accept that Radiohead does not want to be friends with you. If you do see Radiohead at a party and attempt to chat them up, let's just assume the night's gonna end in shattered glass and a broken nose. Hey wait a second... That sounds like the makings of an EXCELLENT Radiohead song! In that case, knives out!

+ Dear Paris Hilton, here's an idea in brief: GET OVER YOURSELF. Your birthday was last month! Why are you s-t-i-l-l celebrating it?? There are way more important things going on in the world... like Britney Spears' comings and goings, for example. I understand that you are rich but it does not get to be your birthday every day. Just sayin. xoxo. Buzzworthy. (Celebuzz)

+ Speaking of, Britney returned to her Disney roots! She took her two boys to the Magic Kingdom this past Thursday during a break from her three-ring... er... Circus Tour. (Fame Crawler)

+ Good news/bad news: M.I.A. did not in fact name her bundle of joy "Ickitt." (NME)

+ Just when we hoped Lindsay Lohan had finally abandoned her singing career, she dropped this little tasty nugget: she wants to cover -- wait for it -- a Britney Spears song. Stay tuned for a La Lohan'd version of either "Womanizer" or "Oops!... I Did It Again"... or not. (Perez Hilton)

+ Have you heard the CSI remix of Taylor Swift's "You're Not Sorry"? 'Cause as hard as I try, I CAN'T stop listening, and it's becoming a bit of a problem. (Teen Hollywood 411)

+ Paging Dr. Drew! Looks like we've got a hot new prospect for next season's Sober House! Rapper Coolio tried busting through LAX this weekend with a load of crack cocaine. (I've heard crack's definitely on the list of things you're not supposed to take on planes.) RidiculouslyDumb.org! (MTV News)

+ The big O has spoken, and she thinks Rihanna and Chris Brown should "take some time" apart from each other. On Friday's live Oprah Winfrey show, Opes also said this whole matter "makes me so sad." Join the club. (Rap-Up)

+ The Jonas Brothers are playing PANAMA on April 15! Hit it, David Lee Roth... (JonasHQ)

Just as I was drifting off to sleep last night, in that weird not-quite-sleeping/not-quite-awake state, I was stricken with a thought so intense that I was propelled forth out of my bed and swept away to my computer, causing an unfortunate mishap whereby my Archi-Teddy was knocked to the floor and almost eaten by my dog!

Anyway, that thought was: What on EARTH has America's favorite Idol runner-upper/ full-time Cutie von Cuterson David Archuleta been up to lately?

In case you too were wondering what David Archuleta's been up to, here's the latest Archu-scoop. "ROP!"

+ Always a do-gooder, our Archi-baby recently joined DoSomething.org as the (cutest! sweetest! little) face of their newly launched campaign on disaster relief. And he's exclusively focused on REAL disasters, people... not these sorts of disasters). (Archuleta Fan Scene)

+ David is on tour! His shows are mostly sold out (duh) but he's getting some rave reviews along the way so far. (See previous "duh.") (Boston Herald, Star Exponent)

+ Arch Madness is under way! There are clues, and codes and it all seems slightly confusing, but I'll play because it's probs lots of Archie fun! (David Archuleta Network)

+ We're all, obvs, still kind of reeling over the news that Archie's gonna be on an upcoming Hannah Montana episode! Miley Cyrus + David Archuleta!? FULL ON BEST OF BOTH WORLDS! (Buzzworthy)

+ David made a video in the Atlanta Airport, and he said POO!!! OOOH! (Just Jared Jr.)

+ David will be on Radio Disney with KSM (yay!) and Jesse McCartney (mmm!) tomorrow! (Archuleta Avenue)

Phew! Lots of Archi-tivities to stay on top of -- and I will stay on top of them all!

Love to love u, Arch!

Just in case you've been doubting that old "anything's possible" cliche, we hereby submit the following mindblowing fact for your consideration: Britney Spears' baby daddy and Olympic-level has-been "rapper" Kevin Federline is starting his own line of children's clothing. (!!!)

[.................................]
[!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!]

Truly, this information scrambles our brains and renders us speechless. BUT, it's true (really... we swear!) and we need to move on. So rather than attempt to determine what qualifies the prince of "Popozao" to produce pint-sized pants, here are our top 5 potential names for Kevin Federline's new children's clothing line.

5. E-List: Kathy Griffin has cornered the entire D-List market, which means E is now wiiiide open! Make E-List happen, Kevin.

4. L'il Gold Diggerz: Wink, wink, nudge nudge.  Too bad that whole Britney thing blew up, but with $5,000 a week coming your way, you can still live it up kinda large? Or at least medium?

3. Vegas, Baby: This one is kind of my fave, because baby is in the title! Yay!  And, as we all know, K-Fed can't get enough Vegas, so it works on that level too. Genius marketing!

2. Stripped: As in strippers... who, uhm, K-Fed seems to enjoy quite a little bit. And who says a grown-ass man with 18 bajillion kids and no discernible job can't enjoy the presence of an exotic dancer. Am I right fellahs?

1.Wanna(bay)BE: Get it? GET IT?

FedEx, if nothing else, you are a master of reinvention. Or at least the reinvention attempt. We can't wait to buy our very first K-Fed endorsed onesie!

For our latest installment of "Buzzworthy Twitters With," let's say twhello to our favorite Daddy formerly known as Puff, Diddy!

His tweets are in bold, our responses are in italics. Herrrre. Weeee. Goh!

I'm back!!! I was a little under the weather. Partied a little to hard. Lol   5:24 PM Feb 26th from TwitterBerry
Oh snap! It's hard out here for a pimp. We feel you, Diddy.

I feel very overwhelmed!!!. What do you do to help with that. Help me!!!   12:47 AM Feb 27th from TwitterBerry
Well, yoga might be cool? Or knitting? OR maybe starting a new reality TV show?? We hear that's kinda relaxing too...

In a stolen car on sunset with jonah hill and hype williams. Somebody call the cops!!!! Lol I'm serious   2:01 AM Feb 27th from TwitterBerry
WHAT THE?? A. You roll with Jonah Hill? That is amazing! LOVE him! B. Why is your ass in a stolen car!? C. Speaking of reality TV shows, Diddy Dispatches People To Junior's For Cheesecake Or To KFC From Behind Prison Bars would be *such* a killer show.

Having tantric sex!!!! I feel so much better.!!! Thank you   8:29 AM Feb 27th from TwitterBerry
Wow. Why. On. Earth. Did. You. Tweet. This. WHHHHYYYYYYY??? Please don't tell me Sting was involved. (Washing my eyes out with bleach).

For all those just tuning in. I'm 6 and half hrs in on a 36 hour tantric sex session. Welcome    3:59 PM Feb 27th from TwitterBerry
Uhm, Dear Dids/ Pappa Diddy/ Pops: please stop talking about gettin' busy. We don't want to have to beg, but we're not above it either.

If anyone is with q tip. Tell him to call me pls!!!!!   9:03 PM Feb 27th from TwitterBerry
Yo, Q-Tip Twitters too! Direct message dat ass (are there ANY celebs not in the Twitterverse now?). Also, thanks for not mentioning tantric sex again.

I believe I can fly!!! I'm flying!!! You can fly to if too if you would just BELIEVE!!!!! BELIEVE!!!!!! Do you BELIEVE??????   6:37 AM Feb 28th from TwitterBerry
You know what Diddy, we USED TO believe. But after following your 36-hour tantric Twitter sex fest, we no longer believe in living anymore.

We believe in Twitter and Diddy... but please, no moar tantric, dude. See you round the Twitterverse! Until then, appropriately, R. Kelly...

+ Mazel tov to Lindsay Lohan! The soon-to-be shana maidela is allegedly converting to Judaism for girlfriend Samantha Ronson, and we here at Buzzworthy would like to be the very first to welcome her to the tribe... and get on the guest list for her upcoming Bat Mitzvah. (+2 pls??). (Celebuzz)

+ Are Rihanna and Chris Brown back on again (!?!??!??!!?) They spent time this weekend at Diddy's compound near Miami. And Chris Brown showed the world he's sorry by going Jet Skiing. (MTV News)

+ ALSO, Rihanna's father has no probs with this latest development. (People)

+ ICYMI, a little movie called Jonas Brothers: The 3D Concert Experience came out this weekend. And if you happened to go catch the flick at the Palisades Center Mall in NJ, you may just be waking up from your real-life Jonas encounter fainting spell. YES, this is real life. (Gothamist)

+ MOTHER CHUCKER!--Blair and Serena are going to just DIE. Like d-e-a-d. Word on the street is No Doubt is going to perform on the May 11th season finale of Gossip Girl. (Stereogum)

+ Looks like U2 frontman Bono + Coldplay frontman  Chris Martin narrowly avoided adding their names to our Top 5 Celebrity Brawls list. You see, Bono was TOTALLY "just joking" when he called Martin a "completely dysfunctional character and a cretin." OH and also a  "wanker." That was a joke, people!  Can't you take a j-o-k-e?? (Perez Hilton)

+ Miley Cyrus went jogging with her HAWWWWWTNESS "special friend" Justin Gaston. We only have two words for her: sports bra (D Listed)

+ Dear all tween stars: please be more like Taylor Swift. She just posted a fab "on the road" video blog that's beyond awesome. (Celebrity VIP Lounge)

+ KANYE WEST'S new VH1 STORYTELLERS EP WAS ON THIS WEEKEND, AND SURPRISE SURPRISE (!), YEEZ WENT ON A WHOLE BUNCHA RANTS THAT NEEDED TO BE EDITED OUT OF THE SPECIAL. EXPECT AN ALL CAPS RANT ON HIS BLOG REGARDING HIS "CREATIVE SPIRIT BEING SUFFOCATED" OR SOME SUCH OTHER B.S. IN 3... 2... 1...(E! Entertainment/ Rolling Stone)
