On Monday, the Jackson family’s publicists released a “preliminary and subject to change” list of participants, which included Carey and confirmed an earlier report from CNN that Jennifer Hudson would take the stage.
Other stars set to appear include:
Andrae Crouch Choir
Family friends Ron Boyd and Pastor Lucious Smith
Shaheen Jafargholi of Britain’s Got Talent
Martin Luther King III
Bernice A. King
Rev. Al Sharpton
Sources confirm to PEOPLE that the dancers who were set to take the stage with Jackson on his London tour will also perform at the memorial.
Beyoncé and Whitney Houston are also said to be making appearances, but are not performing, according to Entertainment Tonight.
According to reports, the Jackson’s will have their own private funeral at Forest Lawn Memorial in the Hollywood Hills Tuesday morning, prior to the public event. The Jackson family, along with Michael’s three children, will remain by each other’s side at both services, says a source. “The news is really setting in now as more family members pile into town,” says a Jackson family insider.
Adds a family source, “Lots and lots of family” will be coming in for Tuesday’s memorial. “We’re talking about 300 cousins and 40 grandkids and great grandkids and some of the old acts the Jackson 5 used to perform with, like the Chi-Lites will be there.”
“The plan is for everyone to be together,” says the insider.
