Rihanna Tapped as Next Armani Underwear Model

Move over Megan Fox! Barbadian superstar Rihanna has been cast as the next face (and body) of Emporio Armani Underwear and Armani Jeans.

The sexy new ad campaign launches in September.

This isn't the singer's first foray into the spokesmodeling world.

RiRi has appeared in ads for such brands as Gucci, Vita Coco, Nivea and, of course, easy breezy Cover Girl.
