Jenny Lewis, Anna Paquin, and that little guy from Jerry Maguire -- all grown up.
BY RI KENNEDY
10. Jonathan Lipnicki
Sure, he kind of looks like a Backstreet Boy today. But can you believe that this is the kid who stole all of Tom Cruise's thunder in 1996's Jerry Maguire? ("The human head weighs eight pounds!") Now nineteen, he may have traded in the glasses and the cute catch phrases for a fake ID, but he's no doubt ready to show you the money.
9. Madeline Zima
Remember that baby face and ever-present nasally voice? That's Grace Sheffield, who gave our TV screens a charming little bounce and some one-liners as she trailed behind Fran Drescher in The Nanny from 1993 to 1999. But most recently she's ditched the schoolgirl uniform to mount David Duchovny in Showtime's Californication.
8. Christine Lakin
Christine Lakin played Al Lambert in the early-nineties sitcom Step by Step. She was the tomboy who got her kicks from sassing her siblings and annoying her parents. When Step by Step ended in 1998, Lakin dropped off the radar — until recently, when, in an unfortunate turn of events, she co-starred with Paris Hilton in The Hottie and The Nottie. She played the "nottie" to Hilton's "hottie" and required extensive make-up to make her look less attractive.
7. Jamie Bell
Jamie Bell starred in 2000's Billy Elliot. Remember that tiny dancer? He's lost the tutu and gained some upper-body muscles and a love of mugging for the camera. He'll soon be seen in Steven Spielberg's Adventures of Tintin, as well as (we're guessing) many a girl's (and boy's) bedroom walls.
6. Lacey Chabert
Chabert got her start playing precocious Claudia Salinger on Party of Five. Next to Neve Campbell, Jennifer Love Hewitt, Scott Wolf, and Matthew Fox, she was the nerdy little sister. But when she reappeared in 2005's Mean Girls, she was funny as hell, and very grown-up, at last having shed the turtlenecks for sexier ensembles.
