Congratulations to Danica McKellar and hubby, Mike Verta!

The former Wonder Years star, and current math genius, is finishing up her first trimester and the couple could not be happier about the new addition.

Awww, I love it when child stars grow up to be healthy, functioning adults. It restores faith in humanity. I've said it before, somebody did something right on the set of The Wonder Years - Winnie and Kevin are both doing great!

All right Danica, the bump watch is ON.
