Rihanna poses topless!

The R&B artist appears shirtless, with her arms wrapped around her breasts, in a new ad for Nivea.

Rihanna has partnered with the skin care line to "bring Nivea's 100th anniversary celebration to fans all around the world."

The company, which is sponsoring the singer's U.S. and European tour, said it chose RiRi to spearhead its "largest ever digital mobilization campaign in social media" because "no other world star has more fans on social networks like Facebook than Rihanna."
