Taylor Swift had more than music on her mind as she worked the red carpet at the 2008 Country Music Awards – the singer, who famously used to date Jonas Brother Joe Jonas, 19, told OK! what she thought of her ex-boyfriend's decision to go public with his new older love, 10,000 B.C. actress Camilla Belle, 22.

"They've been together since we broke up," Taylor tells OK!. "That's why we broke up - because he met her."

Swift says her best advice for getting over a heartbreak is to "write songs about it." When OK! asked if she and Joe are still friends, Taylor curtly replied, "We don't talk."

Joe and Camilla met on the set of a Jonas Brothers' music video. An insider says the couple only started dating after the video wrapped.

How professional!
