If you're not materialistic, Madonna, then right now, send me $1 million.  right now.  You're not materialistic and it would just be walking around money/chump change to you.  Prove to me personally that you are not a materialist, I'll be waiting.  from digitalspy:

Madonna has reportedly revealed that she is not a materialistic person.

The singer admitted that people often assume that she is because of her 1985 hit 'Material Girl'.

When asked if she was "materialistic" by the Daily Star, she said: "Everyone relates that title to me because of the song I did 300 years ago. It's a title I got stuck with.

"When I first did the song it was meant in an ironic way, as I don’t think of myself as a materialist person (sic). I hate that name but I do love clothes and fashion and I love beautiful things.

"As the years went by, strangers would see me in the street and would shout, 'Yo, it's the Material Girl' and I was like, 'Ahh, I'm not, I hate that name'. However, I realised I needed to get a sense of humour and embrace it."

It was recently reported that Madonna has been offered a $1bn Vegas residency.
