David Beckham has, let's not deny it, a pretty amazing body. And, while he may be retired from football, he's certainly not retired from the world of underwear advertising.

Which is just as well, actually. Because, judging by the new teaser clip of this new ad for H&M, he's still got a lot more to offer in this department!

In the spot, David is locked out of a photo shoot on a rooftop wearing only his underwear. With no way down, he goes to great lengths to find a way back inside, performing all his own stunts in the process.

Fans will see Beckham zipline across rooftops, scale buildings and navigate tricky obstacles all in his signature briefs - but, if they vote over at the official H&M website, the ad will go one step further.

Yup. David Beckham could very well be NAKED at the Superbowl this year!

In the #covered version of the ad, Becks ends up at a photo shoot wearing only his H&M briefs. In the other, more salacious version, fans can vote #uncovered and have Beckham arrive clad only in his birthday suit.

David Beckham recently spoke about how excited he is to be starting the new campaign.

"It was so exciting to work with one of my favorite directors, Nicolas Winding Refn, on my new campaign for H&M/

"Nicolas pushed me hard to create an action-packed film, which shows off this season’s new heritage-inspired bodywear at its best."

The Final ad will air during the Super Bowl on 2nd February. We just CAN'T predict how fans will vote...
