Her attitude surprised those present, who had expected unanimous support for the project. Jermaine's Reaction Jermaine's reaction was swift. The older brother, whose son Jaafar Jackson is making his acting debut portraying Michael, stood up and confronted Janet harshly: "You're going to miss this wave. You're so jealous. Just ride the wave," he reportedly said, according to a Page Six source. The moment stunned the younger family members, unaccustomed to such open conflict between the siblings. Later reports indicated that the argument continued over the phone. A TMZ insider claimed that Janet had always been jealous of Michael and that, although she had the opportunity to participate in the production, she chose to decline. However, Taj Jackson, the singer's nephew, tried to quell the rumors on social media: "Don't promote false stories or lies. This is our MJ party and you are not invited." The film, which also stars Colman Domingo as Joe Jackson and Nia Long as Katherine Jackson, will be released in theaters on April 24. Meanwhile, the Jackson family proves that Michael's legacy continues to generate passions… and divisions.
