As for highlights, of course "Grease" changed my life and I will always be grateful for that experience.

I am not embarrassed to say that when I was at my worst I took anti-depressants because I think people need to hear that. I think if you are in a dark place where you can't pull yourself out, you may need to ask for help.

I simply have a marvellous life, a very lucky life.

There's a kind of a line between music and math, so I guess I got the music gene, thank goodness. But my mother wasn't too thrilled. She wanted me to go to university and get a degree or do something, and my father, he liked opera so he wasn't too thrilled either, because he wanted me to be an opera singer and I didn't have - as he said, I don't really have the strength to do that.

I love seeing young girls and their parents and grandparents at my concerts all loving the music from Grease when I perform those songs (and yes, I do perform a bunch of them!).

My biggest mistake was my best lesson... you don't learn anything when everything is going perfectly.

I love clothes. I don't know a woman who doesn't. But generally women are intrigued with fashion. Designers are almost making fun of us at times.
