The tween world is atwitter. It looks like a prince and princess of the Disney Channel kingdom have started dating, with insider stating that Nick Jonas, 15, and Selena Gomez, 16, are definitely an item. Selena shows up in the Jonas Brothers' video "Burnin Up" and was featured in a photo with Nick in the August issue of Rolling Stone. Nick's rep says, "They are not girlfriend and boyfriend. They're friends. All of the Jonas Brothers are friends with Selena." But romance or not, both Nick and Selena are committed to chastity, with both of them wearing promise rings, so maybe it's just a platonic kind of love?
