Madonna's Very Private Performance

Got an extra half a mil lying around somewhere? Well Madonna wants your money if you do! Madge is planning on auctioning off a very private performance on her upcoming tour--but she's hoping to raise around $550K for the performance.

The lucky winner and a pal will be treated to an exclusive two-song show backstage on Madonna's "Sticky & Sweet" tour.

She tells Gigwise.com, "People have offered me millions to play at their Bar Mitzvahs." Half a mil for one performance? Sounds like a steal! Okay, not really, but it would definitely give you bragging rights for years.
