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 cried on my 18th birthday. I thought 17 was such a nice age. You're young enough to get away with things, but you're old enough, too.

I was always a little bit chubbier than everyone else. But I would feel pain for some of the other girls, who were so young and felt they had to be so skinny. They'd be living in the model apartments, totally wrapped up in this whole world. And it made me more sad than anything.

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.

Beauty comes from the happiness within.

I've been spending this last month trying to find four outfits to wear to the different premieres of The Two Towers. It's hard work.

I've always enjoyed acting, but there's a part of me that's shied away from living a celebrity life. I don't feel comfortable being noticed all the time. Sometimes I even fantasize about doing things other than acting. But I can remember being back on set the third day of my latest project and going, "Ahh, this is what I have to do for a living." It's what makes me happy.
