That was fast! Joe Jonas has moved on from ex Taylor Swift and is now rumored to be dating 10,000 BC actress Camilla Belle. Apparently, Joe likes to do things quickly. When Joe called Taylor to break things off, she said he spit it out in less than 30 seconds!

How'd Camilla make her way into Joe's heart? "They met on the set of his music video," a source tells People. "All the guys always had thought she was really pretty and that's why they asked her to be in it. It was only after doing the video that they began to date."

Are Camilla and Joe more compatible than Taylor and Joe were? "She's a really good girl and it seems they share a lot of the same characteristics and morals," the source says. We hope they can make it work -- we can't bear to hear any more breakup songs about a Jonas!
