Roseanne Barr eviscerated her former TV son Michael Fishman in an expletive rant after he spoke out about her 2018 racism controversy last month.

“He f–king doesn’t even f–king know what I said,” she claimed in an upcoming episode of the “Can’t Be Censored” podcast. “Even though I’ve explained it 10,000 times for nine years on the internet.”

Barr, who appeared on “Roseanne” with Fishman from 1988 to 1997, claimed he “hasn’t even taken the time to listen” to what she has to say and labeled him a “brainwashed bigot.”

According to the actress, Fishman — who portrayed her onscreen son, DJ Conner, in “Roseanne” — had asked Barr to explain her rant to him in private after she had already tried to before, and so she gave him a heated response.

“I told him, ‘Let me explain this to you, Michael. Go and f—k yourself and stay f—ked until the day you die. Don’t f—king put my name in your f—king mouth. Shut the f—k up.’”

Barr said that Fishman will never understand what she said because the Democratic party has been “shoved down [his] throat and up [his] ass.”

She continued, “F—k you. You have no geopolitical context whatsoever to discuss what I said. Go f—k yourself you little f—king worm.”

The comedian also claimed that she was the only reason why he was brought back for the “Roseanne” reboot in 2018.

“I was the only reason you were on that show. They wanted to get rid of you in the reboot and I made them take you back. F—k you, you little f—king putz,” she concluded.

Page Six has reached out to a rep for Fishman for comment.

As Page Six previously reported, Barr launched a racist tweetstorm in May 2018, which targeted Chelsea ​Clinton, George Soros and former Obama adviser Valerie Jarrett.

The following day, she issued a blanket apology and announced she was leaving Twitter.

“I apologize to Valerie Jarrett and to all Americans,” Barr wrote. “I am truly sorry for making a bad joke about her politics and her looks. I should have known better. Forgive me-my joke was in bad taste.”

Shortly after her horrific rant, ABC canceled the “Roseanne” reboot, which had just premiered two months earlier.

Days later, her feud with Fishman kicked off with Barr claiming her sitcom son threw her “under the bus” — after he “vehemently” condemned her racist tweets.

The actor, notably, went on to star on ABC’s “The Conners,” which was a direct continuation of the series “Roseanne,” just without Barr.

Last month, Fishman defended ABC’s firing of Barr while noting that “good people make mistakes” and that he “love[s] the one who made this mistake” and “always will.”

“I’ll always have compassion and love [for Barr], and I’ve shown it continuously and she helped the world understand that good people can make mistakes,” he said.

“But there was no joke. There was only damage and dehumanizing — and perpetuating racial tropes leads to real-world consequences.”
