1. LACEY CHABERT

Hometown: Purvis
Claim to fame: Before she ever tried to make "fetch" happen in Mean Girls, Chabert started off as the cute younger sister in Party Of Five and went on to parody her co-star, Jennifer Love Hewitt, as the hot chick Amanda Becker in Not Another Teen Movie. Look out for the dark-haired knockout in two movies this year, neither of which have a release date yet: A Holiday Heist and Slightly Single In L.A.
