She's been peppering her Instagram account with a series of smouldering shots from her latest photoshoot - and her latest, taken while she straddles a surfboard off the coast of Copacabana Beach, is perhaps her raunchiest yet.
Indeed, Rihanna is snapped striking another sultry pose as darkness falls over the picturesque Brazilian hotspot.
With a rather dubious looking hand-rolled cigarette perched between her lips, the 25-year-old songstress appears to be gently paddling the board towards shore.

Rihanna shows off her curves in a gold bikini, her back arched and shapely rump exposed as she navigates the water.

The Bajan singer and model is notorious for posting photos of herself from various photo shoots, Tuesday was no exception.
Rihanna, who is arguably more comfortable wearing a bikini than clothes, looked in her element while posing on yacht.
Letting the photo speak for itself, she chose not to caption the photograph which sees her with one leg outstretched, her arms holding onto a metal railing while giving a seductive stare into the camera lens.

With her array of tattoos on display, Rihanna oozed confidence in the shots, set against the choppy blue South Atlantic Ocean.
The star wore her cascading raven locks in beach waves, which delicately framed her face, while showing off her enviable bronzed and toned physique.
Her photos are all to feature in the latest edition Vogue Brazil, and the photo shoot has taken place over a week to make sure that there is an interesting mix of locations and outfits.
