Madonna was booed off stage by fans who had paid Â£195 per ticket for a concert lasting just 45 minutes.
The performer left angry crowds demanding a refund at the end of the gig in Paris, France.
Attendees at the Olympia venue claimed she spent just half an hour singing and the rest talking about politics".
The show was a last-minute addition, added to her touring schedule in an attempt to smooth things over with the country's far-right National Front party.
They threatened to sue her for flashing an image of a swastika superimposed on the face of the political party's leader during a concert earlier this month.
She said during the show last night (27.07.12): "I know that I made a certain Marine Le Pen very angry with me. And it's not my intention to make enemies...it's my intention to promote tolerance. And when we can start saying that we have to get rid of this person or we have to get rid of that person, because then we'll have a better place, it starts to sound like something else; it starts to sound like something scary.
"So the next time you want to point the finger at somebody and blame them for a problem in your life, take that finger and point it back at you."
