Nina Dobrev had another gorgeous bikini-clad outing when she swam with turtles in Honolulu on Friday. The former Vampire Diaries star showed off her toned figure as she emerged from the water in a pink and blue high-waisted two-piece by Kore Swim. The 28-year-old is currently on the island to film a documentary on shark conservation. She was spotted with shark behavior specialist and conservationist Ocean Ramsey as they looked over their footage, which Nina gave fans a glimpse of on Instagram. "These beautiful creatures were so friendly and serene gliding peacefully in the water," she wrote with the hashtags "#HelpSaveTurtles #ProtectWhatYouLove #ProtectTheHonu." Just a few days earlier, the duo lived life on the edge as they swam with sharks without a cage.
