Danica McKellar’s sexy Maxim photos have tongues a-waggin’ for anyone that was ever hot for Winnie Cooper from The Wonder Years.

Winnie Cooper… er… Danica McKellar strips down to bra and panties and strikes some seductive poses in the Maxim spread.

Let’s not forget that Danica McKellar is also a math geek – the actress is a mathematician set to released her third book, “Hot X: Algebra Exposed.”

Of the book, McKellar says, “Let’s make math fun and sexy and glamorous. Smart is sexy, that’s one of my main messages.”

From the looks of Danica McKellar’s Maxim photo spread, I’d say she’s getting the sexy message across just fine.

The Maxim pics must have been taken a few month back – McKellar is now pregnant and expecting her first baby later this year.
