Home has always been wherever I am. I'm not very attached to walls - or people, for that matter - so I've always loved travelling around. A book in my back pocket, a diary, and a pen is all I need to call any place home.

Music, for the moment, has been this hidden thing for me. For the first time, I am master of something. I am not used by someone else, like in movies or pictures, where you always have the happiness or disappointment of knowing it's you seen through someone else's point of view. You go to see a film and half of the pretty scenes are not in it-the ones you liked. Living with this frustration all the time, suddenly music came as the best thing for me at home, where no one can tell you anything.

It's true that the biggest value of life is that it's going to stop. I was thinking when I was in New York the last time that all that we see that has importance is man-made. It isn't nature-made. And when I was looking through the window, looking at New York, I was so moved by humanity's desire for immortality-because that's what it is.

I always have lipstick, and use the same lipstick for my cheeks as blush, so that it looks very natural. It's a good trick I learned from my mother. I like NYX or MAC because they have a lot of pigment and they're matte.

Singing is the rawest thing. Having been naked in films or naked in photo shoots, it's nothing compared to singing. It's absolute nakedness. You are stripped bare! It's very strange. Acting seems much easier, in fact, because you are putting on a costume - whereas here you are taking everything off.

I always loved singing, but I thought it was like drawing - just something you do in your own little corner to calm yourself down. But when my friend, the French songwriter Etienne Daho, listened to my songs, he was so moved that told me that I had to do a demo, share them with the world.

It is impossible for me to get involved in films that I don't like, so I just wait for a project that really tickles my fancy.
