High School Musical star Zac Efron is set to shock his fans by posing with a naked woman in an arty new photospread.

The actor agreed to roll around on the dirty ground with a nude model as part of a session for the upcoming Interview magazine. In one shot, readers will be able to see the model's exposed right breast.

He says, "It was definitely different from anything I had ever done before."

It's not the first time the squeaky clean 21-year-old has seen a naked woman - nude cellphone camera shots of his girlfriend Vanessa Hudgens caused a storm of controversy last year when they were leaked onto the Internet.

The candid snapshots Hudgens took were meant for her absent boyfriend's eyes only.
