Taylor:Joe Started Dating Camilla Months Ago

Joe Jonas broke up with Taylor Swift over a 27-second phone call last month but now the 18-year-old Fearless songstress claims that Joe and 10,000 B.C. actress Camilla Belle were together even before that.

“They’ve been together for months,” Taylor tells OK!. “That’s why we broke up.”

Joe, 19, and Camilla, 22, started to get to know one another when she starred in the Jonas Brothers video “Lovebug.”

“We saw her in [10,000 B.C.] and, to be honest, we all fell in love with her,” Joe’s younger brother, Nick, has said. “We said why not have her in a music video?”
