Hey, guess what? You can't steal another band's name, dude. A judge ruled that Tommy Lee's band has to change its name after the finale of CBS' Rock Star: Supernova, because another band already has the name 'Supernova'. The original Supernova is a punk trio out of Orange County, California. They filed suit earlier this summer and got an injunction yesterday to prevent CBS, creator Mark Burnett and every member of the band from performing or recording under the name Supernova.

The new Rock Star band, whatever they're going to be called, goes on tour starting on December 31. Maybe we'll find out their new name when they crown a winner tonight?
