Behind The Scenes At The ‘Be The Change’ Youth Ball — Check Out Our Live Blog!

Our crack reporters are live-blogging from the backstage of our “Be the Change” inaugural Youth Ball, featuring Kanye West, Fall Out Boy and Kid Rock, and reports from Kenya, New Orleans and Washington, D.C. For a look at what went on during the rehearsals earlier in the day, head here — to start this blog off, we’ve got Gil Kaufman as he warms up after waiting outside for an hour …

Gil Kaufman 9:20 p.m. Cool, I didn’t miss much while I was waiting outside, and right now, Kid Rock is killing it … in a mellow, sit-down-and-chill, summer-breeze kind of way.

Gil Kaufman 9:49 p.m. Usher just swept into the house. He’s one of our correspondents for the night and he’s cabbage-patching to Bell Biv DeVoe’s “Poison” as wife Tameka Foster, decked out in an elegant, eggplant-colored, floor-length gown looks on and laughs.

Daniel “Monty” Montalto 9:50 p.m. It’s official: The Youth Ball is now the hottest ticket in town! No kidding, I just heard of one big-time A-lister who was looking to get in but was having a hard time even getting a ticket.

Shaheem Reid 9:52 p.m. Fonzworth Bentley and legendary NBA villian/ forward Bill Laimbeer are holding court on the dance floor — not dancing, having a discussion.

Daniel “Monty” Montalto 10:10 p.m. Kanye West just took the stage and everyone in the place ran toward the stage like there was an emergency. Then again, there kinda was: ‘Ye was bringing down the house with a medley that kicked off with “Touch the Sky” and “American Girl” and went into some of his biggest pre-808s and Heartbreak hits. Virtually everyone is now on the right-hand side of the room, where Kanye is playing. Even the bars are empty! And Kanye is KILLING IT — and taking the black-tie dress code to levels that make me feel underdressed (of course) …

Gil 10:17 p.m. I saw one of Kanye’s bandmembers earlier in the night and he was wearing this crazy black face shield that looked like a welding get-up. I actually thought he was here to do some emergency repairs …

Monty 10:20 p.m. Fall Out Boy were out in full force watching Kanye’s performance from the side of the stage. Not too long after Kanye left the stage, the crowd broke out in to a chant of “O-BA-MA!” reminding everyone that no matter how hot Kanye’s performance was (and it WAS), Barack is headlining this show …

Shaheem 10:21 p.m. Kid Rock arrived in Washington, D.C., today, just in time to hear Barack Obama speak. “I listened to it,” he said. “We had just gotten off the plane. We were in the van, but that’s the important part: Listening to it.”

Gil 10:21 p.m. Ashton Kutcher and Demi Moore just arrived.

Shaheem 10:23 p.m. Obama chants are echoing throughout the ballroom. The crowd actually had an extra two pops during “Love Lockdown.” People started setting up American flags on the stage, away from Kanye. That’s where the Obamas will be for their dance.

Speaking of dancing, there was a couple ballroom dancing throughout Kanye’s whole set!

Monty 10:32 Kid Rock, Tobey Maguire and Ashton Kutcher are all hanging out together by Sway’s position, waiting for the president …

He’s here! The place is going bonkers!!!! I’ve never seen Bush greeted like a rock star, but to this room, Obama is even bigger than that. Everyone in the room has their cameraphones up in the air to catch this moment.

Benjamin Wagner, 10:35 p.m. Even Ashton Kutcher is snapping iPhone photos on an MTV News homebase crowded with Demi, Kid Rock, and Usher. The crowd is chanting “Yes we can!” Obama laughs …

Gil 10:33 p.m. Ashton and Usher gave each other a bro-hug on the MTV riser, then, a few minutes later, stand together to watch President Obama address the crowd.

Shaheem 10:50 p.m. It’s too much to talk about: I just shook hands with Spiderman. Right before the Obama’s came on, Tobey McGuire, Ashton Kutcher, Demi Moore, Kid Rock, Usher and his wife Tameka all came to the MTV homebase to watch the speech and dance. Ashton taped the whole thing on his camera; Usher got most of it too. When Usher was called away right before the band started playing, Ashton turned to him and said “You’re gonna miss the dance!” “You can’t miss the dance,” Demi added. But Ush, the professional he is, was focused and hit the floor for his TV appearance.

Afterward, Usher and Tobey McGuire greeted each other.

Benjamin 10:56 p.m. Fall Out Boy met Obama 10 minutes before tearing through “Thnks Fr Th Mmrs,” which they dedicated to ex-President Bush.

Shaheem 10:57 p.m. Funny moment: After Ashton and Demi had their interview with Sway at the MTV homebase, Ashton yelled to the crowd, “We did it!” His wife must have not heard. As they were walking down the steps, she said, “Give them a little wave. Did you give them a wave,” she said about the crowd. “Oh, I did,” he answered …

Shaheem 11:01 p.m. Singer Eric Benet is walking around the ball … by himself! Poor guy …

Monty 11:10 p.m. President Obama and the first lady came through here like a slow-dancing tornado. I heard they were behind schedule, but it felt like they were here for a flash. The prez spoke a bit and gave the crowd some love, then they slow-danced to an instrumental version of “At Last.” Afterward, Obama said, “That’s what’s called old school,” getting a big laugh out of the crowd. And just like that, the president and first lady were gone.

Monty 11:13 p.m. Fall Out Boy just ended their set with “Sugar We’re Going Down” and like ‘em or not, anyone who says those guys don’t put on a good show has never seem ‘em or is a liar. I actually just heard that the guys got to meet Obama prior to taking the stage — something none of them had ever done, despite being early, vocal supporters of the new prez.

Gil 11:14 p.m. There is a photographer in the photo pit who totally looks like ex-Vice President Dick Cheney — er, without the wheelchair.

Gil 11:15 p.m. Kanye just walked by and I was blown away by his crazy faux-hawk, wedge-sideways fade hairstyle. That dude really is on some outer space ish …

Gil 11:30 p.m. The crowd is still going strong, grooving to Britney’s “Womanizer” and the remix of T.I.’S “Whatever You Like.” Here’s the thing: I’ve been to something like five balls this weekend (it’s surprisingly easy to lose count) and all I could think of them was, “You paid a thousand bucks for this?” But tonight? Kid Rock, Kanye, Fall Out Boy and the president? I woulda paid to be here! (Just kidding, boss …)

Monty 11:39 p.m. Sway is getting ready to interview Fall Out Boy and Kanye together — which can only be a good thing, since the last time ‘Ye and FOB got together, it resulted in the amazing “This Ain’t a Scene, It’s an Arms Race” remix. Let’s hope Kanye gets inspired to do something with “America’s Suitehearts,” which definitely brought down the house tonight.
