Rihanna's Proves to Be Quite the Contortionist

(Greece) Sexy singer, Rihanna, showed off her flexible chiseled body as she continues her European tour on her Instagram account by doing a bunch of provocative poses in odd angles for her fans.

The sexy singer is now infamous for posting edgy sexual pictures of herself as she globe trots during her music tour on the internet and each time the photos seem to push the line further and further.

With Miley Cyrus getting as much attention for being naked on a wrecking ball and Kim Kardashian posing practically naked post-pregnancy, it's no wonder the pictures female celebrities need to get attention are becoming racier and racier, the question is, when is it too much?
