Joe Jonas

The second oldest of Disney's favorite family act, Joe Jonas didn't begin his young career as the breakout bro among the Jonas Brothers -- that honor belonged to third Jonas Nick, who got the trio its first record deal. But somewhere between the Brothers' debut in 2006, their appearance on, like, every Disney soundtrack since then and the Disney Channel's ridiculously successful original movie Camp Rock, Joe became the Jonas to beat: He took on a good chunk of the lead vocals, played a starring role in Camp Rock and gained a lot of new fans for "Gotta Find You," his solo on the Camp Rock soundtrack, and "This Is Me," his chart-making duet with costar Demi Lovato.
