Madonna is facing a legal wrangle in Paris after failing to heed French politician Marine Le Pen's warnings about her stage show.

It's not the flashing of the pop star's breast that has incensed the Front National party leader - but the screening of a video that juxtaposes a swastika over Le Pen's head.

The far-right politician warned Madonna there would be consequences if she aired the video she debuted at a gig in Tel Aviv, Israel at the beginning of her MDNA tour at her concert in Paris over the weekend.

Le Pen now plans to sue the singer after she ignored her warning and showed the video as part of her performance of Nobody Knows Me at the Stade de France on Saturday.

Le Pen's aides have confirmed a private plaintiff's case for public insult will be presented to the Paris courts in the coming days.

And Front National vice-president Florian Philippot says, "We can't accept this! It's a very serious insult. Marine Le Pen is defending her own honour, but also that of the Front National's members, its supporters and its millions of voters."

In June, Le Pen's father Jean-Marie Le Pen suggested his daughter should ask Madonna for $1 million.

Meanwhile, Madonna is scheduled to perform another concert in France in August when her MDNA tour hits Nice.
