France's National Front on Tuesday branded Madonna a "Granny Gaga" after the global pop icon became embroiled in a new row with the resurgent far right party.
Madonna had enraged the FN in 2012 by showing a video depicting its leader Marine Le Pen with a swastika over her forehead at a Paris concert.
She took another swipe at the party on Monday with a post on her Instagram account.
The post featured the front page of French newspaper Liberation from May 26, the day after the FN topped the polls in European elections with a record 25 percent of the vote.
The page shows a triumphant Le Pen celebrating the victory next to the headline, "FN France".
Madonna's caption read: "Russia. Ukraine. Venezuela ...., now France?!!!!! #fight Fascism #fightdiscrimination #fightlynchmobmentality #fighthatred#fightforffreedom #revolutionoflove
FN vice-president Florian Phillipot responded with a sarcastic suggestion Madonna was seeking controversy to court publicity at a time when her career has been eclipsed by the global stardom of younger rival Lady Gaga.
"In politics too, Granny Gaga has lost the plot," Philippot tweeted.
