Nelly is set to join a star-studded line up including Lil Wayne, Nas, and Snoop Dogg in an ad campaign for the Sean John clothing line.

"I have been a big fan of Diddy and the Sean John clothing line for years," Nelly said in a statement. "So, when they asked me to work with them, it was a real honor. I hope my fans will enjoy this campaign as much as I did shooting it."

Nelly will make his mark with the successful clothing line by serving as an underwear model for the brand's newly launched underwear and loungewear line which is said to include briefs, boxer-briefs, boxers, undershirts, pajamas, robes and much more.

"I have known Nelly for many years and I really admire his work. To me, Nelly is the quintessential definition of the Sean John man," Diddy explained in a statement. "He has the attitude, the swagger, and most of all the physique that our customers can both aspire and relate to. And let's be honest, all of the ladies out there are going to be thanking us for this campaign."

In addition to his new modeling gig, Nelly is also prepping for the release of his newest effort, "Brass Knuckles," which is expected to his stores September 15.
