When I really treat myself, I go to incredible Leonor Greyl in Paris for a head massage.

I don't mind being called Supernova. If one nickname is going to stick, that's not a bad one!

Because of my childhood where I was constantly by myself, I always feel lonely. I have a lot of people that I absolutely love and I know love me but I can't get rid of that feeling of loneliness no matter who I'm with - even with my children.

When you are at the bottom, you find beauty in such little things, and goodness in such little gestures. When I compare any struggle today to ones that I may have had in my childhood, there is nothing that can bring me down.

The secret to applying my makeup is that I just put it where it's needed.

I live a very different life now, with incredible privileges, but looking back I realise that growing up in Russia gave me tools that other people don't necessarily have - such as the will to push that bit further, to make things happen, to succeed.

I don't want to have strong arms, like you get from Pilates or yoga. But dancing arms become your best accessory. And it's great for your core muscles.
