Danica McKellar

Danica McKellar stole our adolescent hearts with her cat eye specs and pigtails as the one and only Winnie Cooper on the late '80s/early '90s sitcom, The Wonder Years. She has since appeared on shows includingThe West Wing, How I Met Your Mother, Inspector Mom, and the 18th season of Dancing With The Stars, and shares a kiss with Avril Lavigne in the singer's music video for "Rock N Roll." Nerds everywhere rejoice: this babe is also a pro mathematician and New York Times bestselling author.
