I think the most important beauty lesson I've learned from my mom is to be happy in what you do.

I never thought that I'd be considered to have a good body. I was bony up top and kind of dumpy on the bottom.

The adrenaline of a live performance is unlike anything in film or theater. I can see why it's so addictive.

My drive is something that I don't fully understand.

In Britain, they have a lot of laws to protect you, and we enforce them very strongly so that our children can stay private figures, and the British press leave us alone, which is great. It means we can go on the Tube into the centre of London because it's quicker and more fun for the kids. We can do normal things.

Beyoncé's like, 'Okay. The singing is great. But you're not having any fun.' She's like, 'Remember when we were at Jay's concert and Panjabi MC comes on and you do your crazy Indian dance? Do that. Be you!'

By 40, all women are amazing.
