OK! Exclusive: Chris Brown's Got Milk Ad

Chris Brown, 19, joins the ranks of past Got Milk stars including Taylor Swift, Miley Cyrus and even his own girlfriend, Rihanna, to show the world just how milk does the body good!

The Grammy nominee and three-time American Music Award winner showcases his buff bod in the new ad, which debuts Dec. 12 in Rolling Stone.

OK! got this exclusive behind-the-scenes pic and a sneak peak at the new ad featuring the tattoo-clad “Run It” singer in his milk ‘stache.

The ad reads, “Chris Brown feat. Milk. Another great collaboration? Milk. Some studies suggest that teens who drink milk tend to be leaner and the protein helps build muscle. So eat right, exercise and drink lowfat or fat free milk. Talk about a smooth move.”

Chris will be touring in Europe throughout January and returning for the Grammy Awards on Feb. 8, where he was recently nominated for two Grammy Awards for Best Pop Collaboration with Vocals for his song "No Air" with Jordin Sparks and Best Male R&B Vocal Performance for his song "Take You Down.”
