Danica McKellar is the original Blair Waldorf!
The former Wonder Years star posed for a sexy underwear shoot back in 2005 for Stuff magazine, but the past five years have been VERY kind!
Danica posed for the upcoming issue of Maxim, in which she dressed as a school girl.
Remember, she writes children’s math books with sexy titles for a living… (Hot X: Algebra Exposed, Math Doesn’t Suck, and Kiss My Math.)
Wouldn’t mind calling her teacher!
