Danica McKellar: Winnie From 'Wonder Years' Is Pregnant!

Remember little Winnie from the Wonder Years series? Well she's obviously all grown up and is knocked up with her first baby!

Math nerd Danica McKellar wondered if she was pregnant but wanted to put off the pregnancy test while she worked on her third book Hot X: Algebra Exposed. Yes, she really writes books about math.

"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! When you do take the home pregnancy test, it doesn't quite seem real. But when you see the baby and the heartbeat on the ultrasound, it's so incredible."

This is the first baby for Danica and her husband Mike Verta. Congrats on your bun in the oven!
