Danica McKellar

From TeeVeePedia, the Internet TV Encyclopedia.

Danica McKellar is not only pretty, but also wicked smart. You don't stand a chance with her, fanboy.

While best known to television viewers for her role as the young Princess Diana on The Wonder Years, Danica McKellar is actually wicked smart. How smart? She has a mathematical theorum named after her! (The Chayes-McKellar-Winn theorum).

Really.

Despite being in line for the Lucasian Professor of mathematics chair at Cambridge, McKellar still keeps her hand in acting, having appeared in guest spots on The West Wing, Babylon 5, and How I Met Your Mother.

Despite her extreme smartness and hotness, McKellar somehow lost out on the role of the most beautiful mathematics graduate student ever to Nav1 Rawat on Numb3rs.
