Usher Gets Down, Fall Out Boy Meet Obama Backstage At Youth Ball

Plus: Ashton Kutcher snaps iPhone pics of the president; Kid Rock hits D.C. just in time.

WASHINGTON, D.C. -- Our nation's capital has been at its absolute craziest over the past few days, and A-listers had their choice of high-profile events to attend in honor of President Barack Obama. But where did the stars flock? Our [article id="1603131"]"Be the Change" Youth Inaugural Ball[/article], of course. And we had the backstage covered, so no odd celebrity pairing or impromptu dance (we're looking at you, Usher) went unnoticed.

First on the stage was [artist id="1230523"]Kanye West[/artist]. We spotted one of 'Ye's bandmembers earlier in the night wearing a crazy black face-shield that resembled a welding get-up. We actually thought he might be there to do some emergency repairs. As West performed a medley of his biggest hits -- including "Stronger," "Good Life" and "Touch the Sky" -- a couple ballroom-danced throughout the entire set. They must have been inspired by the [article id="1603124"]first couple's first dance[/article].

[artist id="1235716"]Fall Out Boy[/artist] were out in full force to watch Kanye's performance from the side of the stage. But the boys were even more starstruck by Obama, whom they met 10 minutes before hitting the stage themselves. They played "Thanks Fr Th Mmrs" -- and dedicated it to ex-President George W. Bush.

The final performer, [artist id="10551"]Kid Rock[/artist], arrived in town on Tuesday (January 20), just in time to hear [article id="1603090"]Obama make his inaugural address[/article]. "I listened to it," Kid told MTV News backstage. "We had just gotten off the plane. We were in the van, but that's the important part: listening to it."

While the three musical acts owned the stage, let's not forget who was the man of honor: Barack Obama. The place went bonkers when the new president arrived onstage, and all the kids had their camera phones up in the air to capture the moment. But it wasn't just the kids -- even Ashton Kutcher was snapping iPhone photos as he stood alongside wife Demi Moore, Kid Rock and special MTV News correspondent Usher. Ashton and [artist id="1270"]Usher[/artist] gave each other a bro-hug a few minutes later and stood together to watch [article id="1603129"]Obama address the crowd[/article].

It wasn't all serious for Usher during the ball. When he first arrived, he did a little cabbage-patching to Bell Biv DeVoe's "Poison" as wife Tameka Foster, decked out in an elegant, eggplant-colored, floor-length gown, looked on and laughed.

When the festivities were wrapping up, Sway grabbed Fall Out Boy and Kanye West for a joint interview. That can only be a good thing, since the last time 'Ye and FOB got together, it resulted in the amazing [article id="1550216"]"This Ain't a Scene, It's an Arms Race" remix[/article].
