It's official: Joe Jonas and Camilla Belle have broken up. "Yes, it's true, they have broken up," Brad Cafarelli, Belle's rep, confirmed Monday. "There is no third party involved and they care deeply about each other and will remain friends."
The 19-year-old rock star, known for his energetic performances, was reportedly visibly saddened during a Jonas Brothers
concert in Detroit last night, especially when he sang "Much Better," a song he penned after he began dating Belle, 22, last fall.
The song is about a girlfriend who is "much better" than a previous girlfriend. The song is widely believed to be a dig at Taylor Swift
, who very publicly dissed
Jonas after he broke up with her.
Though neither Jonas or Belle ever confirmed that they were dating, Jonas was often seen going out to lunch with the 10,000 B.C.
actress. The two met last September while filming the Jonas Brothers' music video "Lovebug." Jonas broke up with Swift soon after meeting Belle but made it clear in a blog on the Jonas Brothers' MySpace page, that he never cheated on anyone.
Jonas is currently in the middle of the Jonas Brothers World Tour, while Belle is filming Father of Invention
with Kevin Spacey.
