I'm 43 years old, and I know who I am, and I own my mistakes. They're my business. And when somebody who doesn't know me has an opinion, it's none of my business.

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.

If I have my daughter in the car and they are making me nervous, I'll do whatever I have to do. I keep a whole log. I take pictures of their cars, write down license plate numbers, everything. If they do it again, I can go to the police. I know my rights and, believe me, I will have them arrested. I will stop at nothing.

It is with hearts full of sadness that we have decided to separate.

I try as best I can to really put all I can into what I'm doing. A lot of days I fail and there's too much to do. I do think it's really important to have time to yourself, whether that's reading something interesting when the kids are in bed or even having a dog.

I used to say to my dad, 'How did you and Mom stay married for all this time?' and he'd say, 'Two things. Number one: You gotta have the same dreams. One person can't be daydreaming about walking down the street in Paris, the other person want to work in a coal mine. Number two: We never wanted to get divorced at the same time.'

Brits are far more intelligent and civilised than Americans. I love the fact that you can hail a taxi and just pick up your pram and put in the back of the cab without having to collapse it. I love the parks and places I go for dinner and my friends.
