Look who's Twittering! It's the Jonas Brothers! And they're on Twitter! FINALLY! OFFICIALLY! ACTUALLY AND FACTUALLY! (Best. Passover. Ever!)

First, if you haven't yet, lest you move another MUSCLE, follow the Jonas Brothers on Twitter at @Jonasbrothers.

The Jonas Brothers posted the Tweet heard 'round the Jonasphere at around 6:30pm ET on Wednesday, April 8. (Don't you like how this is all official-like?) It was short but sweet and straight to the point: Jonas Brothers Official Twitter! (Fair enough!)

As I write this, the Jonas Brothers already have over 15,000 Twitter followers, which is decidedly more than Liam Gallagher @liamgallagher, well over of Yoko Ono's Twitter following (and she's older than all FOUR Jonas Brothers combined, AND she was married to a BEATLE!), though not even close to Heidi Montag's Twitter following (you know -- the one where she talks about hot pink Chanel shorts... and the Bible = a winning combination!)

Also, I just need to point out that currently, the Jonas Brothers's Twitter following also isn't anywhere near Russell Brand's/ @rustyrockets following of over 188,000 Twitters strong. And that, Jonas fans, is yet another reason to follow the Jonas Brothers on Twitter. (Personally, I'm betting that the Jonas Brothers' Twitter following will lap Russell Brand's by the time I hit "publish" on this bad boy.)

Heidi Montag's pregnancy was just an April Fool's joke (ha ha?), but her new song, "Look How I'm Doin'," is no laughing matter. (Though others might disagree.)

If you've been following Heidi on Twitter, you know that, when not eating In-N-Out Burger or making out with Spencer at Lakers games, Heidi's been spending ample amounts of time in the studio with the help of Jesus and songwriter Cathy Dennis -- she wrote the American Idol theme song, Katy Perry's "I Kissed A Girl" AND "Touch Me (All Night Long)" which should not be taken lightly!

Listen to the fruits of Heidi's labors, if you will -- it's feels a little like Britney's "Break The Ice," but the ultimate test will be whether it plays Le Deux... actually, make that Don Antonio's.

+ Plus: Don't miss the premiere of The Hills this Monday, April 6 at 10pm ET!

+ Jay kay, guys. APRIL FOOL'S! But seriously, oh my holy GOD how hot is Twilight's Kellan Lutz in this shoot for Flaunt magazine?  it's UNBEWEAVABLE!!!!! (PopSugar)

+ Electro/disco pop tart Lady GaGa reveals that she performed burlesque and hoovered mounds of illegal narcotic substances while living in New York's Lower East Side. We keep loving this girl more and more. (New York Magazine)

+ JoBro mania has struck once again as the boys sold out all five New York-area dates this weekend.  One mom refuses "to spend a month’s worth of groceries to get two tickets to see the Jonas Brothers" for her daughter.  What is this, Nazi Germany? What is wrong with her?? (The New York Times)

+ Heidi Montag gave the entire world a scare with quite possibly the most gutwrenching April Fool's tweet ever. (Twitter)

+ Um, sorry for all the haters out there but there is no escaping the fact that Britney Spears looks uh-MAY-zing in the new Candies ad campaign. Like, for realz. (Popoholic)

+ It's just another lazy, crazy, hazy day for Chris Brown, shootin' hoops at a college in Virginia. Not a care in the world, that one! (MTV News)

+ Mormons aren't anti-gay! Read this and more trinkets of wisdom from our favorite eyeliner-wearing straight Mormon and Real World: Brooklyn cast mate Chet Cannon. (Towleroad)

+ Beyonce and her sheer shimmer pantyhose took to the General Motors Place stage in Vancouver to kick off her world tour. She is a whole lotta woman.  (ICYDK)

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.

+ Mark Hoppus (@markhoppus) -- He's been Tweeting about blink's new album a lot.

+ Four Year Strong (@fys)
