Justin Timberlake has gotten his post-break up booty -- and Cameron Diaz isn't afraid of getting hers. After hooking up with surf star, Kelly Slater, Cam was spotted cozying up to Blood Diamond Oscar nominee Djimon Hounsou on Thursday, People reports. "It looked like the perfect post-Valentine's Day date," a source says. While there were other peeps at dinner, the pair seemed quite the couple. "They were totally vibing each other, lip-on-lip action," the source says. "Cameron looked so happy... Djimon followed her every move." And Cam and Djimon showed off their moves on the dance floor, where the source says, "they were dancing really close, bodies pressed together."

But are Cam's flirtations making Justin jealous? Possibly. The couple reunited at a bar late Friday evening. While Justin was out at a party with Martin Scorsese, he jumped to talk to Cam when she showed up at 1 a.m., People reports. (A source says she "was low-key, her hair was dark and pulled back.) "Cameron never joined their table," the spy says. "She just showed up and Justin got up and started talking to her. They were being very discreet."

But while they met publicly, there was no P.D.A. going on at the bar. "They weren't kissing or holding hands or anything, but they were being very friendly," says the eyewitness. But who's to say what happened later -- the pair left the bar together a half-hour later!
