Rihanna Wears a Bikini Top in Sardinia, Italy, Pictures

Rihanna made the most of her final hours in Sardinia, Italy, yesterday, first stopping at Prada then partying late into the night with girlfriends. During her latest shopping spree, Rihanna stepped out wearing a sequin bikini top, but earlier in the week she showed off her sexy body in a bright blue bikini and toasted champagne with friends wearing a colorful cutout one-piece. Rihanna's been sailing around the Mediterranean for the past week, but even on vacation she managed to release her latest video, "Cheers (Drink to That)."
