Under Armour quickly debunked a rumor that the former Mr. Star Jones, Al Reynolds Jr., was their new celebrity model. Pictures of Reynolds sporting some Under Armour underwear circulated around the internet for a day or so, fueling conjecture that he may have been tapped to be their very own David Beckham. You have to give it to the guy for being in terrific shape, though.

The details of how Jameswinston Co. Director Brian James found their sole model Sasha Popovic remain a mystery.

"When the true story of Jameswinston Co. comes out it will be a story you couldn't make up," James says.

But as the Jameswinston story comes into focus, so does the career of their hard-working and hard-bodied model, Sasha Popovic. Popovic models every product line on Jameswinston site and he's featured in nearly all of their advertisements. The 27-year-old Slovenian has put on more fresh pairs of skivvies in the last year than many men will ever own. In fact, Popovic now claims he's a convert from commando to briefs.

We had a few brief words with the rising star.
