Camilla Belle and Joe Jonas Break up?

PerezHilton is reporting that Camilla Belle took in a Fernando Verdasco tennis match at BNP Paribas Open from Verdasco’s private box. Camilla and Verdasco were later seen going out to dinner. Allegedly, Verdasco had his arm around Camilla and the couple was spotted heading the resort where Camilla was staying.

So are they still together, if so should Joe Jonas be upset?
