After Victoria Beckham and Megan Fox, R&B star Rihanna has now stripped off to pose in a series of risque photos for the new Emporio Armani lingerie ad. The 23-year-old singer flaunts her figure in lacy inner wear in a photo and poses seductively at the back of a vintage car, Daily Mail reported. In other shots she poses in skin tight jeans and leather jacket as she lies on the top of the car.
