Photos: Rihanna gets butt naked for French mag photoshoot...18+

By now we all know Rihanna has no limits, but these photos are a little shocking regardless. lol. The singer posed totally naked from waist down, and on all fours, wearing just a crop top for a semi-nude photoshoot for a French magazine in LA...

She posed face down, butt up...and even exposed her nipples at a point...with many people on set. Oh dear Rihanna. See the photos after the cut...but please do not open if you're in the office...:-)
