Hilary Duff "doesn't even remember" life before she had a child.

She said: "I feel like I don't even remember who I was before I had him.

"He's taught me about patience, which I didn't have before. Being in this business since I was 12, I constantly was busy and on the go. I think having him has helped center me and calm me down and make me realise that the little things are important."

And the 26-year-old beauty believes parenthood has made her a more confident person.

She added: "I've gotten a lot more confidence as a woman as a whole, not just as a mother.

"In my work and in my everyday life - I think there's a confidence that comes with motherhood."

And Hilary - who split from Mike in January after three years of marriage - even claims her son, who she dubbed a "30lb monkey", helps her stay in shape.

She added to website TooFab: "I was just away from [Luca] for 10 days. After spending the weekend with him, I woke up so sore. My shoulders and arms were dying. And he never sits down. That's a good workout."
