I grew up going to the store, seeing the products [of L'Oréal ], seeing the commercials and the ambassadors. I never in a million years thought I'd be associated with them.

I've tried lots with my hair. Obviously I used to have it as a number one all over, super easy, but then I started to grow it out. I had an afro and then I got rid of the sides.

I think grooming is definitely undervalued by men. We all expect women to be fully groomed, which they do. But I also think it's just as important for a man to look fresh and clean.

I'm constantly watching my weight for my job, and I've trained so hard this year to be ready for this season-more rigorously than ever - but people who tune in to Formula One have no comprehension of what we have to do to be fit. It's so physical. This year, the car is way faster than when you came to the race. And the physicality has gone up quite a lot, at least 20 to 30 percent. People don't see that. They don't see us as athletes. They just see us driving.

I love it in the States. The roads are big, the food is big. If it was possible to be in L.A. and still live my racing life, I would move now.

My brother was told that he wouldn't walk, that he wouldn't be able to play drums, that he wouldn't be able to race a car - and he's done all those things. He's defied the odds, defied disability. I look at him and I'm so inspired, by his mentality and by how incredible the body and the mind are. There's really nothing you can't do. My brother has proved that.

I can't go to the cinema. I go to the bathroom in a petrol station and people come in there for autographs. It's tough but I knew that was going to be the case.
