Children are all unique, so when you're blending families it's really important to get to know each individual child... Being a stepparent can be a really incredible opportunity. Sometimes children pay attention and listen to someone who's not their blood parent. Sometimes I notice how my son Milo learns things from my best friends and people that have been around him, his grandparents and so on, in a way he can't from his own mum and dad. It takes a village!

I just remember saying to myself that I'd much rather do movies than modeling, and that it was worth a try. I didn't really know anything about it. I hadn't seen many movies, or so-called, good movies. When I was a kid, I was obsessed with Star Wars and Night of the Living Dead. When I got more curious about the movies, I thought they were something you had to learn about and go to school for and read every book.

Being a teenage model was lot of fun, like playing dress-up. I'd feel ugly and awkward and chubby, and they'd transform me. Not that that makes everything better. Then my mom shopped the pictures around, I guess, and the agencies started calling. I wound up going with a little agency, Spectrum. It all happened really quickly, I started modeling for magazines like YM and Seventeen, and I did a couple of bigger things like Italian Vogue.

Fathers are very, very important in building the foundations and self-esteem of children. For me, the way that I was raised, consideration, courtesy and manners are really key and I think the father plays a big role in setting an example to children in how to behave out in the world and how to treat people. It's a little bit different when it comes from the dad rather than the mum somehow.

I was really blown away and inspired by everything that she [Audrey Hepburn] had done for children via and through UNICEF and I guess it really, really floored me in a way that I hadn't ever felt toward a public figure before. To see her kindness was inspiring and spoke to me as a person. She was so real and so elegant..I am also inspired by what Angelina Jolie is doing by traveling to places like Cambodia to help children by actually being there and being more involved.

It was so embarrassing, everytime I see it, I blush. Imagine if you saw yourselves like that. It's one thing to get dressed up and do the movie star thing, but I mean, it's my job to be outside of that and it's not like I'm on the outside when they're all watching me.

I think it's healthy for couples to be away from each other for short periods.
