Mario Lopez flexes in his new book...

I'm such a sucker for Mario Lopez photos. I mean, c'mon. Look at that smile, those dimples, those biceps. He's so perfect I could slap him! What makes it worse is the few times that I've met him, he's been unfailingly polite and chatty and the first time, he didn't even know I was a journalist!

Mario, weekend co-host of "Extra," "Dancing With the Stars" runner-up and Slater on "Saved by the Bell," is in NYC appearing on Broadway in "A Chorus Line" and is also taking time to promote his new fitness book. It's obvious that he's pretty much the best advertisement there is for the book!
