(CNN) French President Emmanuel Macron has described his Brazilian counterpart Jair Bolsonaro as "extremely disrespectful" after the South American leader appeared to mock his wife, Brigitte Macron, in a Facebook post.

In a post on Bolsonaro 's Facebook page, a user posted a meme comparing the appearance of the Brazilian president's wife with that of the French first lady, and implying that Macron was jealous. "Don't humiliate the guy ... haha," read the reply from Bolsonaro's account.

The meme was posted in a comment on Bolsonaro's Facebook page.

"He had extremely disrespectful comments towards my wife," Macron said, while speaking at the G7 summit in Biarritz, France, on Monday.

"What can I tell you? It's sad. It's sad for him and for Brazilians. I think that Brazilian women are probably ashamed to read that their president has done that."

"I think that Brazilians, a great people, are a bit ashamed of this behavior," Macron added. "As I have a lot of friendship and respect for the Brazilian people, I hope that they will quickly have a president who is up to the job."
