Joe Jonas and Camilla Belle Photographed Vacationing in Mexico

Things are apparently getting serious between Joe Jonas of the Jonas Brothers and his rumored new girlfriend Camilla Belle. The 19-year-old singer and the "10,000 B.C." beauty were photographed on the beach in Cabo San Lucas, Mexico on November 9, according to Us Weekly.

Joe and his siblings, Kevin Jonas and Nick Jonas, enjoyed their beach day in Mexico earlier this month. And the 22-year-old actress was seen with the boys. "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," the three brothers wrote on their MySpace blog, the same day the photos 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."

Joe met Camilla when the actress starred in Jonas Brothers' "Lovebug" music video, which was shot on September 19. "They are not public about it, but they've been hanging out with their friends and Joe's brothers," a source told Us Weekly. "They're very private."
