Mario Lopez looks so good that it seemed like only a matter of time before we saw him on the cover of a workout book. I can barely remember him now on "Saved By the Bell" when he had that awful hair! I was way more into Mark-Paul Gossler (Zach) than Mario's AC Slater. But no more!

What's cool about Mario's career is that you never know where he's going to turn up next. He's the weekend host of "Extra," he hosts various reality shows, he does guest spots on TV shows - most memorably on "Nip/Tuck" and, of course, there was that runner-up finish on "Dancing With the Stars" which relaunched him into a higher professional gear.

You go Mario!
