Bar Refaeli soaked up the sun with friends while on the beach in Mykonos yesterday. She played on the sand and in the ocean wearing a tiny bikini that showed off her model figure. Bar covered up her two-piece to go waterskiing though. She's been relaxing on the Grecian getaway since last week and has been taking snaps of her exciting trip on Twitter. Bar's just one of many celebrities sharing pictures of their Summer fun, and she shared even more bikini moments of herself over the weekend.
