We thought the big Twilight hotness debate was between Robert Pattinson and Taylor Lautner, but Kellan Lutz is giving his costars a run for their money. He gets sweaty and seriously shirtless for Flaunt magazine, showing off quite the six pack. We've seen him shirtless at the beach with his girlfriend AnnaLynne McCord, but this is a new level for the actor — these photos are hot enough to almost make us forget about Robert Pattinson, almost.
