Heather Graham sported a printed bikini while hanging out at Ipanema Beach in Rio de Janeiro on Tuesday. She splashed around in the waves with her The Hangover Part III costar Ken Jeong before leaving in a red dress and oversize sun hat. But Heather and Ken weren't the only cast members enjoying some downtime on the beach. Nearby, Ed Helms and Zach Galifianakis hung out on the shore in tiny, colorful swim trunks, while Justin Bartha showed PDA with his fiancée, Lia Smith, after a jog near the water. Bradley Cooper also joined the group, walking along the beach before sitting down on a blanket with director Todd Phillips.
The group is in Brazil to promote the third and final installment of the Hangover franchise and arrived in Rio after premiering the movie in Paris over the weekend. Earlier in the day, Bradley spent time shirtless on his hotel balcony, snapping photos of the scenery on his iPhone. The actor has been making sure to document his trip overseas, and even took pictures with fans on the red carpet during the film's Paris and London screenings. In addition to having photography skills, Bradley is in the running for our POPSUGAR 100 contest, so make sure to vote for him!
