Swimsuits you ... Rihanna wears sexy black cozzie
Rihanna places a friendly hand on party pal Cara Delevingne's bum during a tequila-fuelled boat party. The singer was spotted standing with her palm firmly placed on her friend's bikini-clad backside as they laughed and joked with friends on board a luxury yacht. Rihanna, who was wearing a low-cut black swimsuit, which had her initial R emblazoned on the back, and Cara, 20, who wore a black and white two-piece, were snapped as they partied off the coast of Monaco on Friday.
