She was that sweet innocent girl from 'The Wonder Years'.

We all remember her as Gwendolyn 'Winnie' Cooper from the show The Wonder Years. Danica McKellar resurfaced a couple of years ago and turns out she is a big math wiz. Has even authored several math related books. Recently she got together with Avril Lavigne to shoot her next music video Rock N Roll; and let me tell you, they both look super hot ... (did I mention that Danica is 38?!)



With that picture, I can't wait till the video comes out! Here's the official audio in the meantime.
