When thinking of a word that describes John Mayer's fourth album, Battle Studies, the first one that jumps to mind is "transparency." Not only is Battle Studies full of the sort of confessional, emotionally transparent songs we've come to expect from Mayer, but the album's creation itself was a transparent process.

Mayer frequently updated his frequently amusing Twitter (@johncmayer) with Twitpics and info about the recording process of Battle Studies; letting fans in on everything from the construction of the studio to the selection of the cover art.

So it's only fitting that, in the spirit of transparency, Battle Studies is now available in its entirety, a week before its November 17th release.

Head on over to MTV's The Leak and listen to the delicate pop and crunching blues rock of John Mayer's new album, -- including his Taylor Swift duet, "Half of My Heart." It's there for all to hear. And, as a bonus, you watch the video for the album's first single, "Who Says" below.

To borrow a phrase from the always awesome Crunk & Disorderly blog, why won't you let John Mayer be great? This video for "Who Says," from the Mayer's forthcoming Battle Studies LP, is basically the J-Crew equivalent Birdman's "Money To Blow" clip.

We view Mayer's life Soderbergh style; all jumpy cuts and handheld looks inside a life. And what a life! I mean, really, between you, me and the Internet: I WANT THIS DUDE'S LIFE.

Dinner at Blue Ribbon? Why don't you have the steak with a side of steak, and oh yeah, IT'S ON ME. What a mensch! John Mayer is basically saying, 'This is how I roll. Roll with it.'

Sure, there might be some early morning melancholy to deal with, but when is there not some melancholy to deal with when you're up at that hour? And you know what, if I was a sleek guitar expert who could entertain myself with a little 5 A.M lullaby then I would be a totally balanced person. This song is saying, 'We're all free to be you and me.' You do you, John.

+ Shocking news this Tuesday: Amy Winehouse didn't record the James Bond theme for 2008's Quantam of Solace because -- <gasp> -- she was high! Hard to believe, right? (Holy Moly!)

+ No, there is not an official video out for Britney Spears' song "Kill The Lights." It's actually a fan video made by user "Britneli, the winner of "The Britney Global Fan Fiction Contest." It's kind of cute and completely pegs all of Britney's "-isms" -- it almost seems like they were ripped from the "Stronger" video: eyes squinted, hip-to-the-side stances, etc etc. Remember the "Break The Ice" video that was an official  Britney video and looked like something from Akira? (BS Weekly)

+ And no matter what the state of your personal affairs, the only thing more satisfying than a MochaSoyFrappachunkalatteheygirlhey is better than seeing photos of your fat-ass ex-husband at a golf course with other has-been celebs, NOT golfing. (Pop on the Pop)

+ Further proof that Katy Perry is in on the joke... (The Superficial)

+ The Backstreet Boys are really back, y'all. No, like for real. The last time was just bad marketing. This time they are really really back and planning to release a new CD in October (their first single "Straight Through My Heart" definitely sounds like radio will eat it up with a spoon, and there'll probably be like 19 remixes), with a European and headlining North American tour to follow. Alright?? (BackstreetBoys.com)

+ We just HAD to post this little bit of Brooke Hogan doing an autograph signing for 12 people at Wal-Mart in South Florida -- we still can't even get over the album art! WHAT A MESS! (dlisted)

+ P.S. John Mayer is up to his douchey Tweeting again, this time about how the ninth year of every decade produces really crappy music. (MTV News)

The subject of my girl Jessica Simpson is not the most cheery for me right now... That said, this vintage TRL video temporarily sent me to a happy place. First off, Jessica's outfit will put a smile on your face; I had to hit pause just to savor the image. I mean... just watch it. The glittery pink eye shadow, the crimped hair, the leather pants... what a difference nine years makes.

Yes, it was a simpler time, a happier time, when Nick Lachey and Jessica Simpson were still together. While the duet of "Where You Are" from Jessica's 1999 debut, Sweet Kisses, showcases Jessica's fantastic voice (she also knows to turn her head before a belt, sparing Nick's eardrums), my happy moment was short-lived.

Why can't it just be like this again? Vanessa's gone; Tony's gone; John Mayer's gone (wait -- Mayer might not be gone; did you hear that rumor?), so couldn't Nick and Jessica offer each other the perfect comfort? So say her Tweets, Jessica's just sleeping with her mom and dogs and listening to Olivia Broadfield songs right now. Help her! Let the rumors of a reconciliation be true...

Watch the duet from the good ol' days below, intro-ed by a "lonely and untalented" Carson Daly.

+ Word's out that Radiohead's Thom Yorke might be tapped to contribute to the upcoming Twilight soundtrack. Seems like a perfect match. (Rotten Tomatoes)

+ The Beastie Boys have good news and bad news today. Bad news, MCA (a.k.a. Adam Yauch) was just diagnosed with cancer. Good news, he's gonna be ok. He'll just be down-and-out for about two months, and the Beastie Boys' tour is canceled. Speedy recovery, Adam. (MTV News)

+ Here's The Veronicas looking hot in this month's FHM (Australia Edition). (Moe Jackson)

+ UPDATE 4/15/2009: It's official! Demi's doing a 47-city tour with David Archuleta, Jordan Pruitt, and KSM this summer. The tour kicks off on June 21 in Hartford, Connecticut. Get the dates after the jump!

According to Archuleta Fan Scene, Buzzworthy crush David Archuleta and unofficial Jonas Sister/ Taylor Swift's bestie/Princess Protection Program and Sonny With A Chance star Demi Lovato (who's been Tweeting up a STORM with John Mayer, but really, does ANYONE Twitter more than John Mayer?) will be making beautiful pop music together on a summer tour. And seriously, besides peanut butter and bananas, Michelle Obama and J. Crew, Rick Astley and Internet hijinx, and Tokio Hotel and Robert Pattinson (so that last one was probably just a rumor, but still) has there ever been a sweeter pairing than Demi and David?

David Archuleta/ Demi Lovato summer tour dates should be announced soon, and the tour still doesn't have a name, which begs the question: What SHOULD David Archuleta and Demi Lovato's tour be called? Here are a few ideas for your consideration...

1.) The Best of Both Worlds, Part II: I know Miley Cyrus already used this one, but can't Disney share?

2.) Don't Forget... HOW MUCH DAVID AND DEMI RULE!

3.) A Little Too Not Over... DAVID ARCHULETA AND DEMI LOVATO! No? Too obvious?

4.) Believe In Me, Angels: Eh?

5.) Best Of Both Worlds... Collide! FTW!

Got any better ideas? Leave them in the comments. Need some inspiration? Watch Demi Lovato's latest video, "Don't Forget."

Recently in the Twitterverse, Spectacular star Simon Curtis (@simoncurtis) showed Avan Jogia (BOTH Buzzworthy crushes!) how to use Twitter! @MTVBuzzworthy teaching Avan how to Twitter -- Simon is totally Web 2.0, and Avan is totally 2.NO! Avan, get ON THE TWITTER TRAIN! CHEW CHEW!

Ashlee Simpson (@ashwentz) is mesmerized by baby Bronx: i wish i could record every amazing thing bronx does, and watch it over, and over.

Meanwhile Pete Wentz (@ztnewetep) wants to fly to the Congo and see what's up for himself.

Oh, and the INTERNET thinks that Twitter caused Jennifer Aniston to dump John Mayer (@johncmayer). Picky, aren't we?

Furthermore, Dave Navarro (@davenavarro6767) is drinking coffee and is either bored or on a message bored: Having coffee, lurking on the bored, up WAY too early

... And if this is really Dave Grohl (@davidgrohl), then I wish he'd Twitter more.

Also, if you too send me this albeit hilarious (and painfully true) Current TV Twitter video today, you will be the 123848b'thousandth person to do so, mkay?

+ Buzzworthy's Ultimate Guide Twitter Celebrities!

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.

+ 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.

+ 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.

+ 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.
