WASHINGTON, D.C. -- [artist id="1235716"]Fall Out Boy[/artist] aren't exactly heads of state, but while they're in D.C. for the inauguration this week, the guys certainly feel like it.

"We're driving around in bulletproof cars with guys who know mixed martial arts," Pete Wentz told MTV News on Sunday. "The 14-year-old version of your former self is like, 'That's awesome.' "

That awesomeness is what happens when you are invited guests of the mayor and the newly elected president. That's because Fall Out Boy are playing not one, but two inaugural balls this week. (It's worth noting that in classic Fall Out Boy style, the mere mention of "balls" had them giggling throughout the interview).

The first, was Sunday night's [article id="1603001"]Mayor's Ball[/article], where the guys played a set for Mayor Adrian Fenty and his 15,000 guests -- not because the 38-year-old mayor wanted to seem cool to the kids, but because he's actually a fan of the band.

"I met him last night, and he was really cool; he was like, 'I've been a fan for a while,' " Wentz said. "To be honest with you, we got into D.C. yesterday, and I didn't know how I was getting here until midnight the night before. I think the mayor pulled some strings, and we got here somehow."

The second ball they're playing is Obama's official Youth Ball on Tuesday night, which MTV will be airing as part of its "Be the Change: Live From the Inaugural" special. They will be joined by [artist id="1230523"]Kanye West[/artist], [artist id="10551"]Kid Rock[/artist], [artist id="1270"]Usher[/artist], Rosario Dawson and, of course, the man who will by then be 44th president of the United States.

"Obama is scheduled to come through," Wentz said. "He could come through at any point. Right in the middle of the Fall Out Boy set, it could be like, 'Oh yeah, Obama's here, and he's gonna talk.' I can't think of a better reason for us to stop playing."

"Be the Change: Live From the Inaugural" will air live on MTV on Tuesday, January 20, at 10 p.m. ET/PT. MTV News will have wall-to-wall coverage of the event and of the scenes in Washington, D.C., New Orleans and Kenya in the days leading up to the event and in the days that follow.
