LOS ANGELES, April 14 — Zac Efron won Best Shirtless Performance at the MTV Movie Awards yesterday night — and showed how he did it.

The actor won for his performance on That Awkward Moment, presented by Rita Ora and Jessica Alba.

“I don’t know what to say,” Zac told the audience — and that’s when Rita ran up behind him and ripped off his shirt.After flexing some poses for the screaming crowds, Zac walked off stage.

Zac’s spectacular physique has gained him some high praise from his co-stars, particularly Seth Rogen. Seth stars with the actor in new film Neighbours, and admits he was incredibly impressed by Zac’s good looks.

“He’s the sexiest motherf**ker alive,” Seth told chat show host Conan O’Brien.

“My body is like one big bump and his is like 87 different little bumps that come together. It’s like his whole body is like a giant arrow that points to his d**k. It’s like someone to draw your eyes down from his gorgeous face and suddenly it’s like a Plinko game with your eyes.”

Seth went on to joke that he couldn’t hope to impress women the way Zac does. According to the Knocked Up star, Zac has a hypnotic effect on the opposite sex.

“They make a noise I literally never heard before in my life,” he joked. “You could give me three hours with a woman and I couldn’t make her make that noise that they make. I’ve been with my wife (Lauren Miller) ten years. I haven’t even gotten one syllable of that sound.” — Cover Media
