Um…when does Taylor Lautner turn 18 again? The buff young hunk packed on 30 pounds to keep his role as werewolf Jacob Black in the Twilight sequel New Moon, resulting in awesome abs and perky pecs. Taylor showed off his bulked-up body in a debonair photoshoot for the November issue of GQ Magazine.

“When a man transforms into a wolf, all of his clothes get shredded. When he comes back to human form, he’s wearing ripped jeans, and that’s about it. It’s the way it was written. The great thing about this series is we stay true to the books.”

Check out Taylor in the new edition of GQ, on newsstands October 20. New Moon hits theatres November 20.
