Lady GaGa doesn't want to be rich.

The 'Bad Romance' hitmaker - who has overspent by more than £2 million on the North American leg of her 'Monster Ball' tour - says she is not in the industry for the money.

She said: "I spent every dollar I made on my music, my art. Every dollar. I don't wait to get budgets from the label. I do it on my own. I don't give a f**k about money. Unless it's on the stage, I don't want it in my hand."

The eccentric star says she doesn't understand why some people disregard pop music.

She explained: "Pop music is commercial art the way Andy Warhol's Campbell's soup cans were commercial art. I don't know why everyone is so against pop music. I love a good chorus - sue me. It's that f***ing simple."

The 24-year-old singer - real name Stefani Germanotta - said her ultimate ambition is to show people the creative power of pop music with her own exhibition at the Louvre Museum in France.

She said: "My ultimate goal besides making music forever and touring the world over and over and becoming the greatest pop performance art show on the planet? I want a Lady Gaga exhibit at the Louvre."
