Ever had a secret you couldn't tell anyone?

'New Moon' hunk Taylor Lautner revealed one on Monday's 'Jay Leno Show,' unveiling a short clip of his new movie hitting theaters Friday. Lautner talked with Leno about growing up in Grand Rapids, Mich., and tossed footballs around with NFL icon Jerry Rice.

In the clip, Lautner, who plays the shirtless, ripped werewolf Jacob, bounds into the bedroom of Bella, played by Kristen Stewart, as he climbs a tree outside her window and leaps gracefully off the house.
