Joe Jonas and his 10,000 B.C. GF have called it quits. A rep for Camilla Belle tells E! News that the actress is no longer dating the Jonas Brothers heartthrob.

“Yes, it’s true, they have broken up,” says Brad Cafarelli. “There is no third party involved, and they care deeply about each other and will remain friends.”

The pair began dating last year after meeting on the set of the Jonas Brothers video “Love Bug.” Jonas, 19, ditched his singer ex Taylor Swift to be with Belle, but prompted rumors of a breakup during a gig in Detroit, Michigan on Sunday, when he changed the lyrics to the song “Much Better,” presumed to have been a reference to his relationship with Taylor.

Instead of singing “Get a rep for breakin’ hearts, now I’m done with superstars,” Joe sang “Get a rep for breakin hearts, now I’m done with movie stars.”
