Bradley Cooper [1] showed a lot of leg on the set of his film American Sniper in LA on Wednesday. The actor, who is portraying a Navy SEAL in the flick, slipped into a pair of tight khaki shorts to shoot a workout scene, and well, we've never seen quite this much skin from Bradley before. He paired his tiny shorts with a pair of combat boots and a fitted t-shirt with his character Chris Kyle's last name. We've spotted Bradley on the set of the Clint Eastwood-directed picture a lot over the past few months, both alone and with his costar Sienna Miller [2]. Bradley's beefed-up frame [3] — he's gained more than 40 pounds for the role — was front and center in early May, and just last weekend, he and Sienna filmed a romantic wedding scene aboard a boat and shared some pretty convincing kisses for the camera [4].
