How do you get under the skin of a French right-wing politician?

Just ask Madonna, who successfully ticked off National Front leader Marine Le Pen during a show in Tel Aviv, Israel, last Thursday.

According to Agence France Presse, Madonna performed her song 'Nobody Knows Me' in front of a giant screen showing Marine Le Pen with a swastika on her forehead.

The image appeared only for a split second in a montage featuring the likes of Sarah Palin and Chinese president Hu Jintao. However, the photo apparently caused enough of a stir for Le Pen to consider suing.

According to the Daily Mail, Le Pen has threatened legal action should Madonna continue with the performance in France.

Marine Le Pen is the head of France's National Front, a far-right political party that has been accused of racism.

"We are not a Nazi party, and object to being depicted as such," a party source reportedly told the Daily Mail.

The National Front won a record 18-20% of the vote in France's presidential elections on April 22.

Radio France Internationale, an international public broadcaster, reports that Le Pen will be "watching very closely" to see if Madonna does a repeat when she performs in Paris on July 14.
