Zac Efron Gets Dirty

Troy Bolton never scored like this.

Zac Efron, in an extended feature with Interview magazine to promote his upcoming film 17 Again, is featured in a set of racy pics alongside gorgeous -- and topless -- model Edita Vilkeviciute.

"I think it went pretty cool," the heartthrob told the magazine when asked about the photo shoot. "There was, like, a giant sandbox in the middle of a studio, and then I just got to roll around in the dirt for a couple of hours. I got pretty dirty by the end of it, so that was fun. It was definitely different from anything I had ever done before."

The magazine hits newsstands March 24.
