New Couple Alert! Joe Jonas and Camilla Belle

We sense a trend here: The Jonas Brothers have a thing for young, lovely Latinas. First, Nick Jonas linked up with Disney cutie Selena Gomez, and now his big brother Joe Jonas is reportedly dating 10,000 BC star Camilla Belle.

"They met on the set of his music video," a source, referring to the Jonas Brothers' video for "Lovebug." "All the guys always had thought she was really pretty and that's why they asked her to be in it."

But in spite of flying sparks, Joe and Camilla kept it professional on set. "It was only after doing the video that they began to date."

In true Jonas style, expect to see a lot of avoidance and denials from Joe and Camilla that the two are dating. "They are not public about it but they've just been hanging out with their friends and Joe's brothers," explains the source. "They are very private about it."

So how did Camilla become the Belle of the ball? It wasn't just her killer looks. "She's a really good girl and it seems they share a lot of the same characteristics and morals," says the source.

Reps for Jonas and Belle had no comment. Now we can just hope that Kevin Jonas will continue the trend and hook up with his BFF Demi Lovato!
