Braless Rihanna gives revellers an eyeful as she parties in just bikini bottoms and a sheer top aboard mega yacht in the Caribbean

    She recently shared shots of herself soaking up the sun in a stunning red bikini as she spent the Christmas holidays in her native Barbados.

   And by Monday, Rihanna, 26, had hopped across the Caribbean Sea to the island of St. Barts, where she was seen partying aboard a mega yacht.Given the balmy weather, and her penchant for wearing revealing clothing, the sexy singer stepped out in a barely-there ensemble consisting of gold bikini bottoms and a black sheer embroidered top. With her hair set in a high ponytail, the star donned a pair of large hoop earrings as she proudly flaunted her enviable curves while soaking up the party vibe.
