Source: The New PaperMadonna does whatever she wants on stage, but her fans need to live by her rules. The 54-year-old singer threatened to scrap her concert in Chile on Wednesday after she spotted fans smoking in front of the stage during a sound check at the Estadio Nacional, an open air arena. The Daily Mail reported that she lashed out at her fans, saying: "People are smoking right now, no smoking! Where are they smoking? If you're going to smoke I am not doing the show. "You don't care about me? I don't care about you. I'm not kidding. I can't sing if you smoke. Entiendes (understand in Spanish)?" The concert eventually went ahead as planned.
