Danica McKellar has taken her clothes off for Maxim.The former 'Wonder Years' star and author/mathematician is now in her second trimester of pregnancy so she must have done this shoot a few months ago.

"I've always been really cautious about guys who have a Winnie Cooper fantasy, and I'm so glad about that," she told the magazine. "I mean, I can count on one hand the guys I've been with. It was really challenging, but I never gave it up too soon, if you know what I mean."

This is the second time she has done such a pictorial, the other about 7 years ago......bravo for her, I guess being married hasn't changed her free attitude and realizing she needs something to jumpstart her career again besides math books!
