Danica McKellar, who played Winnie Cooper on TV's "The Wonder Years," is expecting her first baby. She's due in the fall, according to People magazine.
She told People, "I was in the middle of a really intense deadline for my book. I wanted to put off the [pregnancy] test because I didn't want any distractions. That only lasted a day - I couldn't stop thinking about it and I caved! You can't try to put that off."
Her third book, "Hot X: Algebra Exposed" hits the shelves in August. She has also written "Math Doesn't Suck" and "Kiss My Math."
Danica and her husband Mike Verta were married last March.
