Jim Carrey's feud with Alessandra Mussolini is getting ugly.

The actor, 57, stirred controversy over the weekend by tweeting a drawing of Benito Mussolini, the leader of Italy's National Fascist Party during World War II and ally to Adolf Hitler, and his mistress, Claretta Petacci, hanging upside down after their execution.

"If you’re wondering what fascism leads to, just ask Benito Mussolini and his mistress Claretta," Carrey captioned his drawing. Mussolini's granddaughter Alessandra was not a fan, replying, "You are a bastard."

The feud didn't end there. While speaking to Variety at CinemaCon Thursday, Carrey offered Alessandra some unfriendly advice.

"She can always flip the cartoon upside down. And it looks like her grandfather is jumping for joy because he just got the head count," he said. "There’s her solve right there. Just turn it upside down. Turn that frown upside down."

Carrey also said that it's a "little disconcerting" that Alessandra, a member of the European Parliament for Central Italy, is in government because "she’s obviously still embracing evil."

Benito Mussolini established a dictatorship in Italy in the 1920s, and worked in concert with Hitler until he was forced from power in 1943. The drawing is based on a photo of the Mussolini and Petacci, who were killed in 1945.

Some applauded Carrey's drawing, with comments including, "I think you’re confusing Jim Carrey with your murderous grandfather" and "Thank you from Italy."

But Alessandra wasn't done, adding suggestions to her own Twitter feed for historical moments the actor might tackle next, including a photo of a slave being whipped and a mushroom cloud.

Mussolini isn't free of her own controversy. She once responded to criticism from a transgender politician with a gay slur.

Carrey is also no stranger to stirring the waters.
