Saint Louis rap star Nelly has been named the first ever spokesmodel for Sean John Underwear, it was announced today (July 28).

Nelly will be featured in the Fall campaign promoting Sean John’s collection of underwear and loungewear.

The campaign, which was shot by Randee St. Nicholas, showcases Nelly in a modern home overlooking Los Angeles, while modeling the underwear.

"I have been a big fan of Diddy and the Sean John clothing line for years,” Nelly told AllHipHop.com 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."

Sean “Diddy” Combs, founder of Sean John, hopes Nelly’s involvement will help boost Sean John’s earnings, which are pegged at about $525 million annually.

"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,” Combs elaborated. “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.”

Styles in the Sean John Underwear line include briefs, boxer-briefs, boxers, undershirts, pajamas and robes.
