During an open-air concert in Santiago, Chile, on Wednesday, Madonna got a bit testy with a fan who decided to visit flavor country in the middle of her set.

If the UK's Daily Mirror is to be believed, Madonna's MDNA tour rider includes one particularly apt request from each venue she visits: Do not enter her dressing room until after it has been scrubbed clean of her DNA.

Madonna apparently doesn't work well with others. She also hates actresses (and Chicago).
