The shirtless hunk, who revealed that he wears Calvin Klein boxer briefs, recently admitted that he gained 17 pounds of muscle for his new role as U.S. Marine Logan Thibault in the upcoming film The Lucky One.
“Physically I started eating a lot. Eating through walls. Just eating and eating. That’s all I’d do and I put on some weight that way. As far as the training goes, just trying different techniques and methods.”
