Whoa! Check Out Mario Lopez in His Underwear

Saved By the Bell actor strips down to his skivvies

Does Mario Lopez spend all his extra time at the gym?

The Saved By the Bell stud is once again showing off his beautiful body—by stripping down his underwear!

The former Dancing With the Stars hopeful is the new face—and abs—of his own line of skivvies called RatedM.

The waistband on one style of his boxer briefs (available on Freshpair.com, by the way) actually reads, "For manful men and their very special guests."

In one pic, Lopez leans against gym equipment with boxing gloves hanging on a wall beside him. In other setup, he strikes a pose in front of a wall of wrenches.

Because we do all our most manly endeavors in our underwear, right?

We kid. But we can't help but reminisce about what Lopez told us back in 2008 when Playgirl offered him a spread. "I politely declined," he said with a laugh. "It's not something for me at the moment. But it's ironic, because I'm, like, 'nature boy.' I'm always running around the house in underwear or nothing."
