The Good Girl Gone Bad singer was posing for the latest issue of the men's magazine where she was seen exposing her assets for the saucy photo shoots, entertainment website idolator.com reported.

The 26-year-old stripped for the renowned Italian photographer Mario Sorrenti, who shot some smouldering hot pictures of her while sunbathing wearing just hot pink underwear.

In one scorching photo the singer was seen lying on her stomach while showing off her toned and bared backside.

Meanwhile, social networking site Instagram has issued a warning to Rihanna for her display of public nudity, entertainment website tmz reported.

Instagram sources told the website that the social networking site sent a warning email to the singer not to publish her nude pictures. If she did, Instagram warned it would permanently shut down her account, the website reported.

The Umbrella singer has never shied away from posing naked for the cameras. Earlier in the month, Rihanna had posed topless for the Vogue Brasil issue while in the past she had stripped down for other renowned magazines like Gq, Esquire and V.
