"I'm not still using it. It was really fun for me for a minute; I wanted to experience something totally normal and also shock people. No one thought I was really on it - and I was really on it!," Dudd said.
Having starred in Lizzie McGuire as a tween, Duff acknowledged that the road to stardom can be "really hard" especially for young actors, reported People magazine.
"I don't know what I would've been like if I had all those outlets to pay attention to... It's kind of scary. It scares me raising my kid."
"As torturous as it has been at some points in my life to be Lizzie McGuire, I think that when that show came out, it was such a part of who I was, I didn't feel like I was playing a part," she said.
