Madonna threatened to cancel a show after she caught a fan smoking during rehearsal.
The 'Girl Gone Wild' singer was angered at someone watching her soundcheck in Santiago, Chile, on Wednesday (19.12.12) after she saw them light a cigarette.
She said: ''There's people smoking right? No. No smoking. Where are they smoking?
''If you're going to smoke cigarettes i'm not going to do a show.''
When the Spanish speaking crowd didn't react, she added: ''You don't care about me. I don't care about you. Alright? Are we going to play that game? I can't sing if you smoke. Entiendes [understand]?
''If you love me then don't smoke. You're looking right at me and smoking cigarettes, like I'm a stupid f***ing idiot.''
Madonna is in South America completing her MDNA World Tour – concluding tomorrow (22.12.12) in Cordoba, Argentina – which has been named the highest grossing of 2012, making $228,406,085 for the 72 shows performed in the year from November 9, 2011, to November 13 2012.
The tour has proved controversial, with Madonna baring her buttocks to raise money for victims of Hurricane Sandy at one date and writing a message of support for US President Barack Obama on her back at another.
Her decision to brandish imitation weapons has also been controversial, attracting criticism from anti-weapons campaigners, although she has insisted they were only used metaphorically.
