Before there was Hannah Montana, there was Lizzie McGuire, and right from the start, you couldn't help but wish that Hilary Duff was your BFF. Lizzie McGuire hit the small screen in 2001, and Duff's lovable character had all the sass and style of one very cool tween. The show ended in 2004, but now the actress has hinted that she would be open to reuniting with her old castmates. When asked about a reunion special, Hilary said, "Would you pay money for that? I love it! I would be totally open to it. My schedule is a little busy right now. But um . . . why not?" Needless to say, we are very excited about the possibility of a reunion. To celebrate, we're looking back on why Lizzie McGuire is the coolest.
