Mitchel Musso

It looks like Miley Cyrus isn't the only 'Hannah Montana' star who isn't as squeaky clean as originally perceived. Cyrus' former co-star Mitchel Musso, who played her friend Oliver Oken on the show, was arrested in Burbank, Calif. yesterday (Oct. 16) for driving under the influence and underage drinking.

Do you recognize Mitchel Musso, who used to star in the Disney Channel's 'Hannah Montana' alongside Miley Cyrus? Well, his music career is really blowing up -- pun absolutely intended. The 19-year-old actor/singer is set to perform at the 2011 New Jersey Festival of Ballooning this summer.

Mitchel Musso recently premiered his video for the song 'Open the Door,' and in the clip, Musso is preparing himself to move on from the heartbreak he endured after breaking up with a girl.
