Corbin Bleu’s newest role will be quite a departure from his High School Musical days!

Bleu told US Weekly at Tuesday’s premiere of Tinker, Tailor, Soldier, Spy  that he “will be naked in 3D” for his role in 2012′s Nurse.

There will be no full-frontal nudity for Bleu, but he says:

“you see my rear end. It’s tasteful. It’s done well.”

There will also be a pretty racy sex-scene between him and 30 Rock’s Katrina Bowden. He says he prepared for that scene by doing:

“a lot of really strict eating — pretty much no carbs of any sort. No pasta, no rice, no bread. My trainer worked me like a dog. I did lots of interval training and lots of weights.”

Sure seems like Corbin Bleu is all grown up now!
