Zac Efron may not have kept his earlier promise to accept his MTV Movie Award sans shirt, but no matter – presenter Rita Ora was quick to assist. The Neighbors star, 26, had Tweeted, “If I beat Thor [Chris Hemsworth] – I’m accepting the award shirtless on stage” back in March, but when the moment finally came Sunday night, Efron’s button-down remained firmly in place. As the audience heckled him, Ora snuck up behind Efron and did the honors, ripping his shirt down to the navel to reveal that the actor had in fact been working on his fitness. All the MTV Movie Awards Winners and Their Thank Yous “I really don’t know what to say, but thank you so much to my fans,” a bare-chested Efron added before laughing and removing the top completely, whipping it around like a lasso. Rounding out his acceptance speech? A flex and salute to the cheering crowd.
