He recently admitted to sprouting some gray hairs, but 36-year-old David Beckham still has one of the hottest bodies in Hollywood.

In the ads for his new Bodywear collection for H&M, the L.A. Galaxy soccer star stripped down to his underwear, revealing his rock-hard physique.

Beckham and his in-house creative team designed the line of briefs, boxers, T-shirts, pajamas and long johns, which will be available in stores and online February 2012. See more pics of David's underwear ads from PopSugar!

"The underwear is totally my designs, and are things that I like to wear," Beckham told U.K. newspaper The Sun.

And while some think of long johns as what you layer beneath a snowsuit, the Brit sports them in a different (and decidedly sexier) capacity.

"I sometimes wear them to go to sleep -- they're very cool," he explained.
