Joe Jonas And Camilla Belle's Breakup Confirmed

'There is no third party involved,' actress' rep tells MTV News.

After some speculation on gossip blogs that the former "Lovebug" co-stars have called it an end, it has been confirmed that Joe Jonas and Camilla Belle have split up.

"Yes, it's true, they have broken up," Belle's rep tells MTV News. "There is no third party involved, and they care deeply about each other and will remain friends."

Fans have posted videos of Joe singing "Much Better" in concert recently, with new lyrics to reflect the breakup. He apparently changed the line, "Get a rep for breakin' hearts, now I'm done with superstars," to, "Get a rep for breakin' hearts, now I'm done with movie stars."

Over the weekend, rumors began swirling that Camilla was hanging out with Spanish tennis player Fernando Verdasco, once again igniting rumors of her infedility. Late last year, Belle had been photographed with Robert Pattinson, despite the fact that she was dating Joe at the time.

Joe and Camilla began dating last November, after Belle starred in the video for the Jonas Brothers' song, "Lovebug," though when the video was shot, Joe was still dating country music superstar, Taylor Swift. And Taylor began making the rounds on talk shows to promote her album, she began to talk openly about her suspicion that Camilla was the reason for their split.

In a MySpace post, the Jonas Brothers addressed Joe's breakup from Taylor, calling rumors that he cheated on her false. "Like all people our age, we are trying to find someone special that we can share time with in our busy lives," the post said. "We all have busy schedules and high demands. We love our life and are thankful for all that we have. We are simply stating that it is difficult to maintain relationships with the kind of life we live."
