There's nobody in the business strong enough to scare me.

If you're presenting yourself with confidence, you can pull off pretty much anything.

I don't care what people say about my relationship; I don't care what they say about my boobs. People are buying my songs; I have a sold-out tour. I'm getting incredible feedback from my music.

Honey, I am the chief of my train. If critics want to hop on board, fantastic. There's plenty of room. The KP train is fun.

You know, when Michael Jackson does the moonwalk, he's showing off! When Prince or Hendrix do a guitar solo, it's confidence! I would hate to be at a show and some nervous wreck is sweating up there and doesn't feel like he deserves to be there.

I don't have to prove anything to anyone, I only have to follow my heart and concentrate on what I want to say to the world. I run my world.
