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 against Robert Pattinson. They're battling it out for the top spots, and we need your help to see which hunky man will take the lead. 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!
