It's very difficult today for girls to become supermodels. There is a lot more competition, a lot of countries in the East have opened up so there are many more models than there were in the Nineties. Now they have to compete with famous actresses but also with, say, reality stars to be on the magazine covers.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
