I try to take care of my hair because it sort of has to withstand a lot of blowdrying and ironing.

Be really, really true to yourself. That to me, has been key to me in understanding how I want to live the second half of my life.

I find the English amazing how they got over 7/7. There were no multiple memorials with people sobbing as they would have been in America. There, they are constantly scaring people, but at the same time, people think nothing of going to see a therapist.

In Britain, they have a lot of laws to protect you, and we enforce them very strongly so that our children can stay private figures, and the British press leave us alone, which is great. It means we can go on the Tube into the centre of London because it's quicker and more fun for the kids. We can do normal things.

Some days I feel like everyone in my world has plugged themselves into my kidney. I'm so tired. But when you're having dinner with your kids and your husband and someone says something funny or you're dying laughing because your three-year-old made a fart joke, it doesn't matter what else is going on. That's real happiess.

As you get older, you choose friends based on not only what feels resonant and warm but if they're bringing something to your life. My women friends are incredibly intelligent. There's no posturing, no competition. Especially in Los Angeles, I see pockets of friends who are very competitive, and I think, What is the point? I would rather be alone in bed with a book than have a girlfriend who is like that.

We’ve been married for more than eight years now and we’re still into it. I think you do fall in and out of love and you just keep going, and every time you go through a really difficult phase, you rediscover something new and it just gets better.
