Rihanna Face Down A$$ Up

These are the Rihanna photos you've been waiting for your whole life -- down on all fours and bottomless. BOOM GOES THE INTERNET!!!

RiRi was posing for pics in the Hollywood Hills yesterday as part of a photo shoot for a French magazine ... wearing some kind of bikini top and nothing else. To make it even hotter, there was even a guy whose job it was to pour water down her back.

To everyone involved with these photos, we say to you ... take a bow.
