Hilary Duff afraid about motherhood

London: Pregnant pop star Hilary Duff, who is expecting a baby boy with husband Mike Comrie, is fretting over motherhood. She says she is ‘a little afraid’ about the responsibilities it entails. "Anything that`s unknown is scary to us, and I`m definitely a little afraid. It`s not something you want to mess up and it`s not something to take lightly," dailystar.co.uk quoted Duff as saying. "Obviously I want to be really good at it. I think it`s the most important thing you`ll do in your entire life, but I have a feeling Mike and I will be okay. We`ll figure it out just like everyone else does," she added. IANS
