The 12 hottest Rihanna Instagram pictures..

11. S&M RiRi

In this picture, Rihanna shouts out to Prada for sending her fabulous custom boots. The only thing is that Prada probably intended them to be worn with a full ensemble, not a thong and some hair extensions. This is just one of many pictures in which Rihanna’s admittedly fantastic behind is hanging out. She probably trains for like 2 hours a day and eats exclusively canned tuna fish and steamed vegetables, so it’s no wonder that she’d want some recognition for her hard work.
