21. After becoming a teen idol thanks to her time as Lizzie, many fans were surprised when Duff chose to take a break from acting, a decision she opened up about in a 2015 interview with PrideSource.
"Everyone thought I was just absolutely nuts because I was really successful and making a lot of money. And it was scary, because there was no guarantee that my career was still gonna be there," she said. "I really needed it personally. I grew up in the spotlight and on tour and with everyone just knowing me and knowing me a certain way. At some point I was like, 'I don't even know if I'm that person anymore, and I don't even have the time to figure that out.'"
She admitted that she found being known as Lizzie "torturous" at times, explaining, "I loved it during the filming. I just didn't know what a success the show was gonna be, and after that...I was still Lizzie McGuire to people and that was super annoying. Now it's not. I don't care now."
