Deb from 'Napoleon Dynamite' Looks Fab

Former child star Tina Majorino is probably best known for playing Deb in the 2004 film "Napoleon Dynamite" ... but boy has she changed.

The 26-year-old -- who starred in "Waterworld," "Corinna, Corinna" and most recently "Big Love" -- looked hip and fabulous at an event in L.A. this week.

Tina isn't a nerd in real life, she just played one on TV film.
