It's hard to believe that nearly 25 years ago, Disney Channel fans were introduced to Hilary Duff's Lizzie McGuire. The hit show, which aired from 2001 to 2004, introduced Duff in the role of 13-year-old Lizzie McGuire as she attempted to navigate the personal and social issues of being a teenager. It quickly developed a cult fanbase that clung to the show's genuine storytelling, fun comedic moments and meaningful lessons about growing up.
