It can be difficult to keep track of all the celebrity tweeting that happens during any given week. It's one thing to obsessively refresh Miley Cyrus' feed to get updates on what Elton John songs she's grooving out to, but how can anybody be expected to know all of the memes John Mayer is trying to start or which former "American Idol" contestant thinks P.F. Chang's is delicious? You can't. But MTV News correspondent Jim Cantiello can, and every week he does in the Tweet Beat.

In this week's episode, Jason Castro weighs in on the nation's airport eateries, Tyra Banks types something crazy about plastic surgery, Yoko Ono fantasizes about dolphins (featuring the secret bonus "The Beatles: Rock Band" level!) and Pink lashes out at Kanye West for his VMA actions. Check out the full report below, and be sure to stay alert for the special cameo from Mr. West himself!

This morning, Adam Lambert tweeted that his eagerly anticipated debut album would be out on November 24. The album — which includes production work from Lady Gaga producer RedOne and Green Day sonic mastermind Rob Cavallo — creates an interesting four-way battle between four former "Idol" contestants, as Carrie Underwood, Kris Allen and Jason Castro will all be putting out records on the same day. Allen of course won this past season's competition, while Underwood has arguably been the most successful "American Idol" victor. And Castro was the laid-back, dreadlocked charmer who shrugged and smirked his way through the show's seventh season. Each album should satisfy a different demographic, but it should be an interesting referendum on which "Idol" has the most staying power.

But which one will people actually buy? We hit the street to ask fans in Times Square which album they would go for first.

The hilariously unscientific results are in, and it's Carrie Underwood by a mile. The country star took home 61 percent of the vote, with many people endorsing the quality of her voice and her crossover status. Lambert came took second place with 23 percent, with many people choosing his style as the thing that would push him over the top. Allen and Castro brought up the rear with eight percent each. There really should be a lot more interest in Allen's album, as he is the most recent winner, but the success of Underwood is a good sign.

This year's "American Idol" has already seen some serious star traffic thanks to return engagements from three of the show's first four winners: Kelly Clarkson, Ruben Studdard and Carrie Underwood. This week, last season's champ, David Cook, is dropping by to sing his new single.

Last week, we asked you who you'd like to see back on the "Idol" stage and by a huge margin, loveable, dreadlocked season-seven strummer Jason Castro beat out the competition. In fact, Castro stole the show with 45 percent of the vote, easily outpacing the tie for second place between season-three seventh-place finisher Jennifer Hudson (who is rumored to be returning to the show) and season-five sixth-place finisher Kellie Pickler, who each got 13 percent of the vote.

So I'm back home in NY and finally on a normal sleep cycle. Hallelujah! And even though I had a three-day weekend to detox from "Idol," I still can't shake one thing I witnessed at last week's Grand Finale...

Nope, not Fantasia's awesome hair. Nope, not the fact that Ruben Studdard was really 9 feet tall in person. Actually, it didn't even happen on the red carpet. It occurred backstage in the press room, and I call it the David Personality Shift.

The two David's made their way to a podium to answer a few questions. First came the Cookster, who just 30 minutes earlier was crowned America's Next Top Clive Davis Slave. We were all expecting him to be over the moon with excitement, or maybe he'd still be crying like he was on TV. (He did, after all, just win a crazy-popular reality show.) But, nope. He waltzed up to the mic, mumbled a few words about his music teacher, then politely smiled and walked off. A few of us turned to each other and said, "He knows he just won, right?" Was it dawning on him that it might be tough for him to break out of the "Idol" mold? Or maybe it just hit him that his first single was a steaming pile of goo? Or, most likely, he was just damn exhausted, and would rather chill with his family (standing backstage waiting for him) than answer silly questions about fashion accessories. (Yes, stupid tabloid reporter who drove everyone nuts. I'm looking at you.)

Conversely, there was ArchuRunnerUp, who haters bashed for his awkward "gosh's" and giggle fits. Several of my co-workers have been "creeped out" by how he often acted like an eleven-year-old boy, as opposed to a seventeen-year-old dude. Well, based on the few minutes I witnessed in the press room, Archuleta was a shockingly mature, well-spoken young man. He finished all his sentences; he didn't gasp for air more than John Goodman on a staircase; he didn't shrug and turn away from the camera like a Harajuku girl. In other words, he came off like the complete opposite he did while on the telly. And he...had...tons of personality! Where was this Archuleta all season long???

Could it be that losing "Idol" was the best thing that could happen to this kid's emotional growth? Was he just freezing on camera all season because of the intense pressure? (Or was he just relieved to finally get away from Seacrest?)

I wonder if this personality shift happened with the other "Idol" contestants. Maybe, behind the scenes, Brooke White was sane, Jason Castro clever, and Syesha Mercado, uh, likeable...?

Editor’s Note: It’s crazy serious and difficult for the US Armed Forces in Iraq, but our soldiers still find time for a little fun and escape: just like many of you, they love their weekly dose of “American Idol.” We made friends on the Internet with some members of the Army’s 82nd Airborne division (Fort Bragg, what up!), who will be sending us their review of each “Idol” installment.

Our soldiers each week (L-R): PFC Joshua Miranda, 22 (Orlando, FL); PFC Nathan Puckett, 19 (Cynthiana, KY); SPC Cory Combs, 21 (Plymouth, MA); and SSG Steve Cody, 27 (Los Angeles, CA)

So, not all of our soldier pals got to catch this week’s “Idol” performances (SSG Cody was the only one who did, and he only caught the last half of the episode), because they were off doing what our nation’s servicemen and women do -- real classified-type stuff. That means there isn’t a complete briefing from our Iraq-based “Idol” hounds this week. But even though he’s halfway around the globe, in one of the world’s most unstable countries, Cody still could tell that dread-head Jason Castro’s number was going to be the one called.

Surprisingly, SSG Cody didn’t even mention Paulagate in his report, but it does seem he’s got a little thing for dark horse Syesha Mercado -- but that’s something he’s got to work out himself.

So last night the “American Idol” crew was whittled down to three. Ciao, Jason Castro! (Cue violins at John Norris’s house.)

Now we are left with David Cook, David Archuleta, and Syesha Mercado, and the competition is really heating up. Because it's great to be in the final three and all -- but how many of you remember the number three's of seasons past?

(Um, we've posted a photo of Syesha above because -- not to be too presumptuous -- let's just say that an office pool of the 29th floor would reveal that most of us are betting our paychecks a David vs. David showdown.)

Can you remember all the number three’s? It may not be as easy as you’d think. Check your answers after the jump. Read more...

So that’s it, brother. You had to know it was coming after Tuesday night…

But let me say this about Tuesday: it may not have been your finest moment, but “I Shot the Sheriff” was a way more interesting choice from the Hall of Fame songbook than the umpteenth version of “Stand By Me” and “Proud Mary.” And for Simon to have suggested “you don’t touch that song”? Huh? As if anything is inviolable on “American Idol” -- please. A sanitized version of “Imagine” is OK, stripped of its atheist, socialist teeth, but a “karaoke” version of Marley’s fight-the-power anthem is not? Spare me the double standard.

Not that I am making excuses for the performance, JC -- not great. And then Dylan -- fine choice, I’d rather hear it than that old classic rock radio wheezer “Baba O’Riley.” But you can’t go up on the lyrics. You said you were “thinking too much” and not just letting it flow. Bad time for that to happen. We all know that you weren't the first one to do it this season, still…

And the outrage in the blogoverse about Jason’s eye-widening, his supposedly “flippant” reaction to the judges, his lack of appropriate remorse over his blown performances, his ever-present smile. WTF do you people think this is? It’s a singing contest! If you ask me, he took it as seriously as “American Idol” ought to be taken. So, let’s see -- when Simon told him to pack his bags, should he have had a “Brooke moment” and broken down? Should he have been shaken to the core? Please. He acknowledged that he “screwed up” two songs he knew and loved, and that’s it. No more penance is needed.

I have to believe at some point -- maybe between Mariah Carey week and Andrew Lloyd Webber week? -- this kid from Texas realized he was in a club that he didn’t really belong, or feel all that comfortable in. Oh well. So much for a little dose of realness in “Idol.” It was refreshing while it lasted.

Congrats, viewers. Now you’re back to the show just the way you like it: polished, scrubbed, respectful, and boring. A future Broadway star, another Daughtry and…(cough) I don’t even know what to call that study in arrested development.

Jason, sorry you got the boot. I doubt you really thought you were gonna win this thing, but thanks for a good run, some nice song choices, and exactly the right attitude. Good luck, dude. It will be a less interesting show without you.

A few thoughts about Paula's “Idol” debacle last night:

Before people get too carried away with the whole “rigging” thing, let’s take a step back for a moment and analyze just a bit.

It may be that what was ultimately revealed last night is that Paula, who’s been more lucid this season than in recent years, has help in formulating her feedback/comments.

All one has to do is watch the show on a regular basis to know that if Randy has anyone helping him with his comments, he or she should be fired immediately. He literally says the same thing, almost verbatim, week after week. “It’s like I say, if you can sing, you can sing anything DAWG!” As for Simon? Come on. Does anyone really think that Simon Cowell is a puppet? Is he going to let others speak for him? No way.

In the end, the best argument against the rigging theory is last week’s results. The judges praised Carly. And she went home. That’s not an anomaly. The public will do what the public will do.

And as for the producers orchestrating a David vs. David finale? The public doesn't need much encouragement to that end. It’s an absolute inevitability having nothing to do with the judges’ commentary and everything to do with the performances they’ve delivered and the followings they’ve built.

What do you think? Is the show rigged? Or was Paula just totally out of it?

Editor’s Note: It's crazy serious and difficult for the US Armed Forces in Iraq, but our soldiers still find time for a little fun and escape: just like many of you, they love their weekly dose of “American Idol.” We made friends on the Internet with some members of the Army’s 82nd Airborne division (Fort Bragg, what up!), who will be sending us their review of each “Idol” installment.

Our soldiers each week (L-R): PFC Joshua Miranda, 22 (Orlando, FL); PFC Nathan Puckett, 19 (Cynthiana, KY); SPC Cory Combs, 21 (Plymouth, MA); and SSG Steve Cody, 27 (Los Angeles, CA)

As President Bush would freely admit, it’s not always possible to meet deadlines when you’re living and working in a war-torn area -- and that’s something we here at MTV News learned last week. With PFC Puckett, who usually emails us the soldiers’ “Idol” commentary each week, taking some much-needed R&R, the rest of the troops slacked, having failed to “make a contingency plan” for Puckett’s time off. So the soldiers sent in their impressions of last week’s performances over the weekend.

While they didn’t comment -- at all -- on Kristy Lee Cook’s ouster the previous week, our soldier pals did think Carly Smithson had redeemed herself, and would be spared elimination. Of course, that didn’t happen. So, how did our valiant troops feel about the “Idol” hopefuls tackling the songs of Lord Andrew Lloyd Webber? SSG Cody said that “ever since my mother took me to see my first play as a child, I have loved the theater. I was happy to see ‘Idol’ take a step in that direction.” After seeing the performances, the guys definitely thought Brooke White or Jason Castro would be sent packing -- which they weren’t.

So, who did they love this week? Who do they want to go all the way? Find out after the jump. Read more...

VIVA CASTRO!!

That’s pretty much all I have to say about Brother Jason’s cover of Bruddah Iz’s version of Sister Judy’s classic “Over the Rainbow.” (Check out Chris Harris’s article on the story behind the song.) Just know that as long as JC keeps delivering the goods like he did last night he is gonna be hard to beat, and the ranks of pro-Castro demonstrators will continue to swell.

Hopefully they won’t have Jason wade too heavily into the cheese tonight, as we all know “Idol Gives Back” has a tendency to approach the line between tastefully touching and treacly…and then cross it. JC doesn’t seem to have much patience for the maudlin, unlike certain other "Idol’"hopefuls.

And one other JC defense: a couple weeks back, Simon suggested that the dreadlocked one didn’t seem to really "care" about the competition. I don’t get that. What I get is that he wants to win, but knows that at the end of the day only one person will. He’s gonna do what he feels, be true to himself, and let the chips fall.

El "Nuevo Comandante" -- Jason Castro. If he wins this thing, for bringing such honor to the Castro name, his namesakes Fidel and Raul should invite him to visit Havana -- one of those "cultural exchange" deals to bypass the long arm of the travel embargo-ing feds. GO, JC!
