Joe Jonas and Camilla Belle have split, the actress' rep has confirmed.

Rumours that that pair had parted ways reached Twitter trending topic status on Monday, after the middle Jonas put in an emotionally-charged performance during a gig in Detroit the previous evening.

Joe had a teary moment while singing I Gotta Find You, and also made apparent references to his split from the 10,000BC star by changing song lyrics.

During Much Better, he sang, "Get a rep for breakin hearts, now I'm done with movie stars”, in place of "...now I'm done with superstars.”

Now Camilla has confirmed the speculation.

"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."

Joe and Camilla hooked up on the set of the Jonas Brothers' video for their single Lovebug.
