Rihanna Poses Nude for Ad Campaign

Nivea cosmetics have recruited Rihanna to be the face of their latest promotional campaign.

The 23-year-old singer posed nude for Nivea's new ad campaign, 'The 100 Years of Skincare for Life,

' which commemorates the brand's 100th anniversary this year. The official promotion will launch in May, in conjunction with the kick-off of Rihanna's 'Loud' world tour, which will now be sponsored by Nivea.

"Over the past 100 years, Nivea has been an iconic skincare brand across the world that is built on the trust of our consumers," Nivea board member Markus Pinger said in a statement. "We are excited to have Rihanna supporting us in our celebration and building a new generation of fans."

The last time Rihanna was in the news for posing nude, the headlines weren't as flattering. Candid photos that RiRi sent of herself to someone with her cell phone surfaced in May 2009. The images surfaced three months after she was infamously assaulted by Chris Brown the night before the Grammys, leading people to believe he leaked the photos, which he later denied.

In addition to prepping for her upcoming tour, Rihanna recently wrapped up a series of high-profile appearances at the Grammys, where she was joined by Drake to perform her single 'What's My Name?,' and at the NBA All-Star Game halftime show where she performed with both Drake and Kanye West. Following her performance at the All-Star Game, Rihanna rang in her 23rd birthday with a lavish, star-studded party sponsored by Nivea
