I go to Malawi twice a year. It's where two of my children were adopted from, and I have a lot of projects there that I go and check up on and children who I look after. It's sort of a commitment that I've made to this country and the hundreds of thousands of children there who have been orphaned by AIDS.
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.
Obviously, I feel a great sense of responsibility being a good parent and raising my children. I don't take that job very lightly. Who they are, what they become and what they contribute to the world is very important to me.
But I love the idea - whether it's in my work or where I live - exploring new frontier, and I like putting myself in strange places and trying to survive and figure things out and gather up an infrastructure. I like knowing that I could figure out a way to live anywhere.
You realise that having a number one record and being loved and adored isn't the most important thing in the world. But at the same time, I don't have a problem with it. What I'm trying to say is, I'm not a reluctant pop star.
I wear the Jewish star, but I'm not - I haven't converted to Judaism, and I'm not - I'm not - I'm not Jewish in the conventional sense because the Kaballah is a belief system that predates religion and predates Judaism as an organized religion.
