Rihanna strips down to her underwear for Armani

Rihanna strips for Armani Jeans and Emporio Armani Underwear ad campaign

Raunchy Rihanna strips down to her underwear – again! – in a new ad campaign for Armani.

23-year-old Rihanna – the new face of Armani Jeans and Emporio Armani Underwear – worked with famed photographer Steven Klein for the sultry black and white photo campaign, which features the singer debuting a white mop hair cut.

The star also appears in a new film shot by Johan Renck, the director behind a number of Madonna's biggest videos.

The film features Rihanna stripping down to her underwear in the back seat of a chauffuer driven car – a clear nod to Duran Duran's notorious The Chauffeur music video – while her track Skin plays in the background.

"Rihanna is a great artist. Her personality, charisma and energy made it a pleasure to work with her. She perfectly embodies the contemporary and youthful spirit of Emporio Armani Underwear and Armani Jeans," says Mr. Armani himself!
