Not to be outdone by Katy Perry and her sharks, fashion risk-taker Rihanna swam with actual sharks for her Harper's Bazaar cover shoot. Anything to get the perfect shot right? RiRi posted pictures from the shoot on Twitter with the very appropriate caption #bucketlistshit. She also tweeted a behind the scenes clip where you can see her descending into shark-filled waters to hammer home the point that she swam with real-life sharks in the name of fashion. Good luck to the magazine that tries to follow this up.
