Bikini-Clad Rihanna Lets Loose on a Luxury Cruise

Bikini-clad Rihanna, in a Charlie by Matthew Zink two-piece, was joined by a group of girlfriends aboard a yacht near Saint-Tropez yesterday. Rihanna's Summer vacation has thus far taken her to NYC, Barbados, and most recently Italy, where she rocked a bright and sexy bikini that showed off her fit frame — have you filled out PopSugar's bikini bracket for a chance to win $500 from Neiman Marcus?

The group worked on their tans, sipped Coronas, rode Jet Skis, and bounced on a water trampoline. The partiers even got a surprise visit from former basketball star Magic Johnson, who stopped by the party to say hello and pose for a quick photo. Rihanna's been documenting her vacation via Instagram and Twitter and even snapped a shot of a paparazzo giving her assistant, Jennifer Rosales, a lift back to their boat after she fell off a Jet Ski. Rihanna's well-deserved getaway could be coming to an end if she wants to make it back to LA for tonight's Teen Choice Awards where she's nominated for her breakout role in Battleship and choice Summer music star. Don't forget, we'll be on the red carpet and inside the press room, so be sure to follow us on Twitter for the latest celebrity news and photos.
