Naomi Campbell and her longtime boyfriend, Vladislav Doronin, left the beach and headed back to their Miami hotel today. The couple drank SmartWater as they dried off, though Naomi's impressive bikini body was still on display. Naomi's had plenty of opportunities to soak up the sun lately, including on a recent trip to Mexico. She and Vlad were some of the lucky guests invited to Philip Green's 60th birthday bash in Mexico, where they played in the sand and partied late into the night alongside Leonardo DiCaprio and Kate Hudson. Earlier this week, Naomi stepped out in NYC to attend the premiere of Cirque du Soleil's Michael Jackson The Immortal World Tour.
