The 2011 shirtless bracket has begun, and we need your votes to determine this year's winner. We've already crowned Halle Berry this year's bikini bracket champ, but which good-looking shirtless guy will join her in the top spot? Last year Twilight hunks Taylor Lautner and Kellan Lutz put forth a strong showing, but this year it's Zac Efron who's taking the early lead. There's still plenty of time to pick your faves and Matthew McConaughey and Jake Gyllenhaal are just a few of the hunky guys that need your votes if they're going to make it into this year's finals. Be sure to vote often and tell your friends, and for all your hard work scrolling through photos of shirtless stars you'll be rewarded with a chance to win $1,000 from J.Crew — happy voting!
