The Jackson family have released a list of stars intending to take to the stage in honour of the 'Thriller' singer, which also includes Brooke Shields, Usher, Stevie Wonder, Magic Johnson, Kobe Bryant, Andrae Crouch Choir and Berry Gordy, says People.
Additionally, Martin Luther King III, John Mayer, Lionel Richie, Smokey Robinson, Rev Al Sharpton and Shaheen Jafargholi of Britain's Got Talent are said to be making appearances at tomorrow's service.
A family source added that many of Jackson's family will be present. "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."
It was recently reported that Jackson's ex-wife Debbie Rowe has decided against showing up at the ceremony.
