Selena Gomez has a lot to do before the 2013 MTV Movie Awards. Things like rehearse for her upcoming "Come & Get It" performance, AND play a little game of "Guess The Nom: Best Shirtless Performance" (which sounds like an AMAZING way to take a rehearsal break, if you ask us). Here's how the game works: We showed Selena a series of famous (and sexy) pecs nominated for the "Best Shirtless Performance" award and asked her to guess which abs belonged to which actor. Selena viewed chests like Daniel Craig's in "Skyfall" (whom she mistook for Ryan Reynolds -- whoops!), Taylor Lautner's from the "Twilight" saga, and finally, Channing Tatum's from "Magic Mike." Apparently Selena's a big Channing fan, because not only did she guess his chest correctly, but she also said, "He's gonna win!" Let it never be said that Selena doesn't have good taste.

Find out who will win "Best Shirtless Performance," and catch Selena Gomez's much-anticipated "Come & Get It" performance at the 2013 MTV Movie Awards this Sunday, April 14 at 9 p.m ET!
