Shirtless Sunday Slurpee: Zac Efron Wins Best Shirtless Performance At MTV Awards

Zac Efron made a promise on Twitter that he’d take his top off if he won at MTV Movie Awards, presenter Rita Ora made sure he didn’t renege.

Back in March, the actor tweeted, “If I beat Thor [Chris Hemsworth] – I’m accepting the award shirtless on stage”, but when the moment finally came last night, Efron kept his buff bod covered in his button-down.

As the audience heckled him, Ora snuck up behind Efron and ripped his shirt off to reveal his rock hard abs and amazing tan. As an added bonus, he also gave us some sexy flexed poses.
