Bradley Cooper is busting out of his clothes!
The actor, who seriously bulked up for his role in the upcoming flick "American Sniper," put his legs and booty on display in a pair of short shorts today on set.
The 39-year-old star reportedly packed on 40 pounds of muscle for his role as real-life SEAL Chris Kyle in the flick -- and it's clear at least some of it went to his butt!
"He's really been working hard. He looks great. He's really taken on this character," his costar Eric Close previously said of Bradley's transformation. "He really takes this story personally and wants to do an honorable job for Chris' memory and for his family."
The movie, directed by Clint Eastwood, is set to hit theaters in 2015.
