I don't feel like my films are about gender; they are about identity - but a different slant on identity.

I don't know if my films are about women in a kind of frolicking - here's a grab bag of women's issues. They are about women of substance with very particular stories.

In May 2006, I had our son, Calder. I spent the next couple of years learning how to be a mom.

In June 2002, I had just finished 'Laurel Canyon' and decided to move back to Los Angeles after nearly a decade in New York. Post-9/11 New York felt different.

Yes, I live a crazy, exciting, whatever life, but I do think it's quite relatable because it has to be - I'm just a girl from St Louis, Missouri that has lived life like anyone else. There are things that are crazy and over the top, but the basic thread is my family, my career, trying to live and pursuing my dreams.

If I didn't get a job, between 16 and 18, that wasn't significant, I was just going to go to college. I didn't want to be a struggling actor at 36 with five kids, doing something I hated. You see the story so much. It's such a vicious business to be in when you're not meant to be in it.

In a sense, the music business and I haven't always been the best of bedfellows. Artists often have to fight their corner. Your music goes through these filters of record labels and media, and you're hoping you'll find someone who'll help you get your work into the world.

Athletes, like everyone else, at times take supplements but just have to consult your doctors and work on that. It's a process, but it's achievable... It's my job to be healthy.
