Bradley Cooper Premieres 'Hangover III', Swims Shirtless in Rio!

Bradley Cooper suits up for the premiere of The Hangover Part III on Tuesday (May 28) in Rio de Janeiro, Brazil.

The 38-year-old actor was joined at the red carpet event by his co-stars Heather Graham, Zach Galifianakis, Ed Helms, Justin Bartha, and Ken Jeong.

The next day, Bradley hit the beach shirtless after the whole crew was spotted out together at Sugarloaf Mountain to enjoy the high sky views!

The day before, Ed and Zach went shirtless on the beach while having some fun in the sun.

FYI: Heather is wearing a Monique Lhuillier dress. Justin is wearing an Etro suit at the premiere.
