KELLAN LUTZ
This former model knows how to work every camera angle, from showing off his otherworldly body in Twilight to heating up underwear sales as Calvin Klein‘s spokesmodel. The secret to the 25-year-old’s sexy six-pack? “I cut back on my candy intake, swim a lot and try to drink as much water as I can,” says Lutz. “That’s the best way to cut up.”
