In her first ad campaign for Emporio Armani Underwear, Rihanna (who rocks a blonde wig in the ads) poses in edgy black and white photos wearing a lace bra, leather jacket and skin-tight jeans while draping her incredibly toned body over the hood and inside of an antique car.

But in her second ad campaign for the underwear brand, the 23-year-old channels her softer, more romantic side and this time, she's taking things to the bedroom.

In the first photo of the spring/summer 2012 campaign, the "We Found Love" singer gives a sultry stare to the camera while donning a very feminine, very lacy bra and panties set. In the other photo, she sports a rather "girl next door"-type lingerie set. And her hair, which is absent from the blonde pixie wig this time around, is done in soft, touchable waves.

The Barbados beauty is the latest celeb spokesmodel for Giorgio Armani Jeans and Emporio Armani Underwear. She follows a laundry list of stars including David and Victoria Beckham and Megan Fox, who've all posed in the Italian label's sexy campaigns.
