The only big things I've purchased are my dad's heart valve and a Rolls-Royce for my parents, for their anniversary. And that was only because my dad had a Lady Gaga license plate on our old car and it was making me crazy because he was getting followed everywhere, so I bought him a new car.

I think there are different kinds of fame. There's fame which is plastic and about paparazzi and money and being rich, and then there's the fame, which is when no one knows who you are but everyone wants to know who you are.

It's all fleeting. As fame is fleeting, so are all the trappings of fame fleeting. The money, the clothes, the furniture.

I'm already crazy. I'm a fearless person. I think it creeps up on you. I don't think it can be stopped. If my destiny is to lose my mind because of fame, then that's my destiny. But my passion still means more than anything.

In the book of Gaga, fame is in your heart, fame is there to comfort you, to bring you self-confidence and worth whenever you need it.

For some people, fame kills it and becomes more important than the music or the performance. But for me fame is like rocket fuel. The more my fans like what I'm doing, the more I want to give back to them. And my passion is so strong I can't sleep - I haven't slept for three days.
