Rihanna's Bikini Photo Shoot Takes a Topless Turn

Rihanna showed off her toned bikini body on Sunday when she took part in a yacht photo shoot in Rio de Janeiro. The singer slipped into a teeny-tiny gold two-piece as she drank Champagne and chatted with her friends and the photographer. It isn't clear if Rihanna's boat shoot was part of a new fashion spread or if it was just another case of Rihanna being Rihanna. The superstar usually has a professional photographer in tow whenever she jets off to an exotic locale, and the pictures often end up on her Instagram page, like they did this time. Rihanna shared a bunch of snaps from her sunny day, including a few racy topless images.

Rihanna may be on the move again this week as she is expected to attend the 2014 Grammy Awards on Sunday. Rihanna is nominated for two awards: best urban contemporary album for Unapologetic and best pop duo/group performance for "Stay."
