Rihanna Dons a Bikini — and Goes Topless — in New Vacation Pictures

Rihanna is topless in one of the new pictures she's just shared from her January vacation in Hawaii. The singer recovered from a big weekend at Coachella by posting a handful of new images on her Facebook page from the late Winter getaway. Rihanna was among the many stars at Coachella in Indio, CA, on Saturday and Sunday. The music festival gave Rihanna a chance to meet up with her pal Katy Perry. After Rihanna's Sunday show, the two girls had a chance to party together. Now Rihanna's back to focusing on her music and film career. She's in the middle of a global press tour for the blockbuster Battleship and is also counting down until the debut of her new single, "Where Have You Been."
