Joe Jonas and Camilla Belle Vacation in Mexico!

Joe Jonas and Camilla Belle are getting serious! The singer and the 10,000 BC actress were photographed on the beach in Cabo San Lucas on November 9. "We are writing this from the beach...doing nothing! First time we have stopped in a while. Can't get better than this. We are already feeling refreshed," Joe, Kevin and Nick Jonas wrote on their MySpace blog - the same day the pictures were snapped. "This week was Kevin's birthday so we took the last day to celebrate his birthday with family, the band, and a few friends," they wrote. "It is so awesome to stop and appreciate all that has happened to us because of all of you." See adorable photos of the Jonas Brothers. The Jonas Bro - who dumped ex Taylor Swift over the phone last month - met Belle when she starred in his new music video for Lovebug, which was shot Sept. 19. "They are not public about it, but they've been hanging out with their friends and Joe's brothers," a source told Usmagazine.com. "They're very private." Like Swift, who admitted she was a virgin, the source told Us that Belle is "a really good girl."

So will they go on double dates with bro Nick Jonas and his squeeze, singer-actress Selena Gomez? "Camilla likes musicians!" the source told Us. How well do you know teen stars?
