Catfight! Kevin Jonas vs. Selena Gomez

Selena Gomez wowed the crowd at the MTV Movie Awards with her performance of "Come & Get It," but there's one person who clearly wasn't impressed her ex Nick Jonas's brother, Kevin! When he was asked who the most overrated pop star today is, Kevin started: "Did you watch the MTV…" but quickly caught himself, saying, "No, no, I'm not going there," of the obvious dig at Selena's performance. "I just think some people should stick to movies," he tried to explain. Ouch- that's a low blow, JoBro!
