In Hollywood, apparently all you need to establish "nerdy" is a pair of glasses, limp hair and some frumpy clothing. Unfortunately, while unusual-looking leading men are plentiful in Hollywood, unusual-looking leading women must be in short supply, because the movies have a tendency to "nerd up" gorgeous young starlets and try to convince us that they are friendless outcasts. In Jennifer's Body, Amanda Seyfried dons the glasses to play the nerdy, less-popular friend of Megan Fox, despite being every bit as pretty -- as if her friend wouldn't give her any fashion tips! Ellen Page will similarly nerd up for Whip It next month, and the pair have gotten us thinking about the other adorable women of Hollywood who have worn the glasses, the lab coats and the sweats of the nerd. Keep in mind that this list doesn't include the generally frumped-up (Cameron Diaz in Being John Malkovich), the nerdy-in-flashback (Drew Barrymore in Never Been Kissed) and the supermodel scientists that aren't even trying (any female mathematician or computer tech in a James Bond movie).
