Rihanna gave the paparazzi an eyeful of her glistening body while vacationing on a yacht in Saint-Tropez in the French Riviera. Fresh off her appearance at the U.K.’s V Festival over the weekend, the pop diva relaxed in a blue bikini, sipping from a glass and basking in the sun with her girlfriends. The hard-working gal will premiere the video for her new LOUD single “Cheers (Drink to That)” tomorrow on iTunes.
