Rihanna has been on vacation and you already know how she does. The singer is known for showing off some of the sexiest vacation photos on her Instagram.
The pop star shared this photo of herself in a bikini on a yacht in France. She gives us a shot from the back which is beyond sexy. I think this has got to be the hottest photo posted on Instagram for the week. Bad gal Rhi Rhi is killing them with this one.
