Singer-actress Hilary Duff wants to keep her son away from a career in show business because she grew up feeling “isolated” as a child star. The 24-year-old, who is expecting a baby boy with husband Mike Comrie next year, was thrust into the spotlight as a 14-year-old with the lead role in Disney TV show ‘Lizzie MCGuire’. “I don’t think there’s a way to stop it – I think kids know what they want but I just pray to God that’s not what he (my son) wants. From when I started to now, the industry is so different. I mean, there’s such an obsession with people’s private lives that I really don’t think was there before,” contactmusic.com quoted Duff as saying.
