Janet Jackson and Niece Paris Jackson Locked in Bitter Feud With Family Over Michael Jackson Biopic

Michael Jackson’s family is in an epic battle over control of his $789 million estate and the hotly anticipated blockbuster biopic of the late King of Pop.

On one side are his sister Janet and daughter Paris, on the other, the rest of the Jacksons, who are hoping the film will help boost the family’s flagging fortunes.

Fireworks exploded when Janet, 59, dissed the movie after a private screening in Los Angeles for about 60 family members.

“As they stood up cheering the movie, Janet began criticizing it,” a family insider tells Globe. “She was like, ‘No! This is horrible. They are doing a disservice.’”

Paris, 28, has long voiced her opposition to the movie. “I just prefer honesty over sales and monetary gain,” she said last year on Instagram, per Deadline.

Their negative comments have infuriated other relatives, who are desperately hoping the film, titled Michael, will resuscitate interest in the “Thriller” hitmaker — and the rest of the family.

Janet’s fed-up brother Jermaine, 71, whose 29-year-old son, Jaafar, stars as Michael, reportedly confronted the “Rhythm Nation” singer after the screening.

“This is finally our opportunity, and we must ride the wave!” sources claim Jermaine told Janet. “It’s an opportunity for our family to get back to where we were [in popularity].”

Euphoria and Fear the Walking Dead actor Colman Domingo, who plays patriarch Joe Jackson in the film premiering April 24, responded to Paris’ opposition to the project, telling WSJ Magazine, “I hope that she eventually loves the tribute that we made about her father.”

Adding to the family tension, Janet is pushing Paris to pursue her court fight to take over the estate of her father, who died in 2009 at age 50 from an accidental overdose.

Paris has claimed that coexecutors John Branca and John McClain are mismanaging the vast fortune and doling out big bonuses to attorneys fighting off a slew of lawsuits accusing the Beat It singer of abuse.

While Branca and McClain vehemently deny the charges, Paris personally showed up for a L.A. Superior Court hearing seeking to obtain timely accounting of the estate’s books.

“There is a civil war ripping the family apart,” the insider tells Globe.
