Teen heartthrob Mitchel Musso began his career as an actor, playing Oliver "Smoken" Oken on The Disney Channel's Hannah Montana before adding a music career to his résumé in 2009. Before he was even in his teens, the Texas native appeared in print ads and TV commercials for the likes of McDonald's and Sony Playstation. At the age of 11, he landed a role in the Michael Caine/Robert Duvall movie Secondhand Lions, playing Haley Joel Osment's cousin (and the nephew of Caine and Duvall). Prime-time movies, guest appearances on TV shows, and a major voice-over role in Steven Spielberg's Oscar-nominated Monster House followed. Musso's work with Disney also afforded him the opportunity to sing on several soundtracks. In 2009, the teen magazine mainstay took his music to the next level when he released his self-titled debut album on Walt Disney Records. The 12-song collection, a musical cross between Hanson and the Jonas Brothers, was followed one year later by the sophomore effort Brainstorm. ~ Todd Sterling
