Miley Cyrus-fever has made its way into politics. Last night, the tween idol had a performance, along with other young stars at the Disney Kids' Inaugural. MTV notes Cyrus as the kickoff act, but Jamie Foxx got the crowd hype with an Obama cheer, complete with beat box.

Malia and Sasha Obama were in attendance. And washingtonpost.com says both are big 'Hannah Montana' fans. The first kids didn't get unruly, though, Mama Obama was in-tow, along with Jill Biden and the Biden grandkids.
