Among the many other celebrities in attendence at Jackson's memorial: NBA icon Magic Johnson, who appeared in Jackson's music video for "Remember the Time;" activist, politician and longtime Jackson family supporter Reverend Al Sharpton; singer-songwriter John Mayer, who performed Jackson's "Human Nature;" Usher, who wore sunglasses as he sang "Gone Too Soon," and scandal-scarred R&B singer Chris Brown.
Almost as important are the familiar faces that didn't show up.
Dame Elizabeth Taylor announced via her Twitter page Monday that though she's mourning Jackson's death, she has no desire to participate in or attend his memorial.
"I just don't believe that Michael would want me to share my grief with millions of others. How I feel is between us. Not a public event," she said. "I said I wouldn't go to the Staples Center and I certainly don't want to become a part of it. I love him too much."
Jackson's first wife Lisa Marie Presley and Debbie Rowe, his second wife and mother of his two oldest children, did not attend. Rowe, who had VIP seats reserved for her, bowed out Monday, just hours after she said she would attend.
"The onslaught of media attention has made it clear her attendance would be an unnecessary distraction to an event that should focus exclusively on Michael's legacy," attorney Marta Almli said in a statement Monday afternoon. "Debbie will continue to celebrate Michael's memory privately."
A Jackson family friend who goes by the name Phoenix said it's probably a good thing Rowe exempted herself.
"I don't think she's sitting too good with the Jackson family right now," said Phoenix, who was in touch with the family this week.
Actor Macaulay Culkin, who hung out at Neverland as a boy and appeared in Jackson's "Black or White" video, was also a no-show.
