The 25-year-old, who gave birth to Luca in March, shot to fame as a youngster playing the title role in Disney teen sitcom 'Lizzie McGuire', but said that she would think twice before letting her little boy pursue a career in Hollywood, reported Daily Express online.
"I'd say, 'Are you sure?' (if my son wanted to act). My sister and I said that same thing to my mom, and she encouraged us. I'm so happy she did, and I would not change my life for anything. But it's tough, and it's totally different than it used to be," Duff said.
"I am even scared of (Luca) growing up getting his picture taken all the time and feeling different. I saw a rag magazine the other day and the headline said, 'Who Wore It Better?' and the photo showed (Tom Cruise's daughter) Suri Cruise and so-and-so's kid.
"I'm just thinking that this is sickening. Now that I'm a mom and I have a child, I can't imagine. It's not right," she added.
