It seems Rihanna can't stop taking her clothes off these days. The 24-year-old singer posted nude photos of herself yesterday, part of a photo shoot to promote her new fragranced called, guess what, "Nude". Rihanna is pictured in a blond wig, covering her modesty with her arm across her breast and her other hand playing with her hair. In the series of four shots, she is opening her mouth and staring at the camera.
