30. Kori Gardner (Mates of State)
Mates of State keyboardist/singer Kori Gardner may be married—that’s her husband, Jason Hammel, on drums and vocals—but that’s never stopped the hot before, and it’s not about to quit now! The über-cute indie rock couple offers plenty or ear- and eye-candy for all comers. On top of it all, the dedicated duo even brings their kids along on tour. New school family values = adorably hot.
