Wow. Winnie Cooper is going to be a mom. That's right, the kid we watched – some of us in original broadcast episodes and not reruns – is having a baby. 'The Wonder Years'' actress Danica McKellar is pregnant. It's the first child for her and husband Mike Verta.

Danica told People magazine, "I'm nearing the end of my first trimester and I'm so excited – I've been bursting to tell people." The 35-year-old veteran of 'The Wonder Years' -- and brainiac mathematician -- has been working on a new book, her third, called 'Hot X: Algebra Exposed.' It comes out in August if you're ready to pre-order it!

Does it take a brainiac to play a brainiac? No, of course not. But when Danica McKellar guests on The Big Bang Theory on January 11, that's what they'll get. Not only is Danica well-remembered as the nearly-perfect Winnie Cooper on The Wonder Years, Kevin's neighbor and the girl he always adored, she's also smart as a whip. She has the degrees to prove it.

A couple of years ago, TV Squad put Danica In the Limelight. Ryan learned that Danica had graduated Summa cum Laude from UCLA with a degree in Mathematics. She is the McKellar in the Chayes-McKellar-Winn Theorem.

For just about every guy growing up in the late eighties and early nineties, Winnie Cooper was your dream girl. She was gorgeous, intelligent, funny and always kind of had that "damsel in distress" aura about her. She was one of the best parts about tuning into The Wonder Years, and so was the actress who portrayed her, Danica McKellar.

Danica started acting early, with a couple of guest appearences on The Twilight Zone, before landing the role of Winnie on The Wonder Years. The show had a great, award winning five year run, but once it ended, Danica did what many child stars fail to do: bow out gracefully. Besides doing a few voiceovers for cartoons, Ms. McKellar spent the next couple of years at UCLA. In 1998, she graduated from there Summa cum Laude, with a degree in Mathematics. Remember the next time you use the Chayes-McKellar-Winn Theorem, because she actually discovered that! Yea, I've never used it either and I have no idea what it means.
