Chuck Liddell and Heidi Northcott Naked in New Ad

We're suckers.

We're taking a video clearly created for viral purposes, and passing it along. It's OK to be a sucker sometimes. And it's OK to gawk at naked semi-celebrities working out. In fact, it's near irresistible. Just don't try it yourself, experts say. You wouldn't want to get your privates tangled in that Bowflex...

The video hit the web amid rumors that it was filmed by a peeping Tom.

That was clearly what Reebok wanted you to believe.

Former Ultimate Fighting Champion and 'Dancing with the Stars' alum Chuck Liddell and busty blonde girlfriend Heidi Northcott work on their bi's, tri's and delt's in the video seen below. Besides their flashy footwear (Reebok ZigTech's, we're told), the fit freaks aren't wearing a thing.

Too bad Liddell and Northcott's most magical muscles are blurred out in the video. You'll have to hope to catch the couple on Chat Roulette for that.

Liddell has been a spokesman for Reebok for some time now. He sparred with Molly Sims earlier this month in support of ZigTech's launch. The shoes, described as an "energy drink for the feet," hit shelves in March.

Northcott, Jose Canseco's former flame and a 2001 University of Southern California grad, is "in a relationship with Charles Liddell," according to her Facebook profile. It's unclear how long they've been seeing each other.

They're clearly pretty well acquainted.
