Teen sensation Selena Gomez has ruled out a romance with Jonas Brothers star Nick Jonas - because she's too busy chasing Shia LaBeouf.

Disney star Gomez, who appears in the brothers' new Burnin' Up video, has recently been linked to Nick - who, at 15, is a year younger than she is - but she insists the romance is all fiction.

She says, "The Jonas Brothers are all sweet. They're so amazing to me. They've become really good friends of mine, but I'm not dating any of them."

And she has set her sights on another young hunk: "I have a crush on Shia LaBeouf. I have a really big crush on him. I want to work with him so bad. I think he's so cute."
