I find it very difficult to wear nice, pretty shoes. I'm much more comfortable in boots or Birkenstocks or loafers.

As a child, I never heard one woman say to me, "I love my body". Not my mother, my elder sister, my best friend. No one woman has ever said, "I am so proud of my body." So I make sure to say it to Mia , because a positive physical outlook has to start at an early age.

The highest compliment I could ever receive about my kids - and I can say that this does happen frequently - is when the in-flight crew say to me, 'Your children are wonderful. They are so well-behaved.' Every time I am told that, I could weep.

When I think about somebody like Keira Knightley, whom I don't particularly know, I see somebody who is working hard, really trying to challenge herself and make smart choices in spite of people criticising her size and performances.

Leo and I are kindred spirits - we're cut from the same cloth.

As a young girl, I never felt attractive. I was fat and unhappy at times, and that kind of thinking stays with you your entire life. There's always going to be a part of me that worries about not looking as slim as other actresses. But at a certain point, when you achieve a lot of your goals and you can be proud of your work, you start to relax more about who you are. And that includes your appearance and self-image - I don't think I look too bad for a mother of two. But women shouldn't have to feel the pressure to compare themselves to actresses or models.

I don't go to the gym because I don't have time, but I do pilates workout DVDs for 20 minutes or more every day at home.
