Tyler Posey isn’t afraid to lose his shirt when it comes to making his next TV appearance a smash…

In the latest promo for MTV’s NYE in NYC 2012 special, the 20-year-old part-Mexican Teen Wolf star, who will co-host the festivities, teases potential viewers with a topless notion:

“I hear if there’s a full moon, a certain shirtless werewolf may run through Times Square naked,” vows Posey while doing push-ups in the clip for the television special, which will include appearances by Selena Gomez, J. Cole, Jason Derulo and Mac Miller. Demi Lovato will serve as Posey’s co-host.

When someone off-camera tells him there won’t actually be a full moon on December 31, he quickly says, “Oh, he’ll probably take off his shirt anyway. I hear he’s been doing lot of push-ups lately.”

MTV’s NYE in NYC 2012 special will air live from Times Square this Saturday, December 31 at 11 pm ET.
