R&B beauty Rihanna has posed topless again for the saucy new cover of French adult magazine Lui.

Rihanna nude on the cover of (issue) seven! Available on newsstands tomorrow

The Umbrella hitmaker was snapped letting it all hang out for the latest issue of the men's publication, in which she is featured sunbathing in a patio chair, wearing nothing but a pair of pink bikini bottoms, with her bare breasts and tan lines on display.

The cover shot, taken by renowned Italian photographer Mario Sorrenti, also clearly shows Rihanna's nipple piercing on her right breast, while in other snaps, the Bajan singer is pictured showing off her backside and lounging completely naked, with just a small towel to shield her genitals.

A representative for the magazine unveiled the image on Twitter.com on Tuesday (29Apr14), alongside a caption which translates as "Rihanna nude on the cover of (issue) seven! Available on newsstands tomorrow".

Rihanna is no stranger to stripping off for the cameras - she has also gone topless for a set of fashionable images in the new issue of Vogue Brasil, although, in that publication, she preserves her modesty with her hands.

She has also previously posed nude for GQ, Esquire and V magazines.
