Audrina Patridge went for a dip in the oceans of Bora Bora on Sunday with her on-again boyfriend, Corey Bohan. He brought his surfboard along for his shirtless swim — he's not in the running this year, but make sure to cast your votes for our Hottest Shirtless Guy contest! Audrina, meanwhile, showed off a bikini from her large collection of two-pieces. She and Corey headed off on a vacation after she was in London practicing her photography skills and promoting The Hills. Her work with the series is finally done after the airing of their finale, and she celebrated the end last month with her many costars.
