One Jackson intimate who will not be in attendance is Elizabeth Taylor, who tweeted her regrets yesterday: "I just don't believe that Michael would want me to share my grief with millions of others," Taylor said. "How I feel is between us. Not a public event."

Eleven thousand fans were selected by an online lottery to be inside the Staples Center; an additional 6,500 are watching a simulcast from the neighboring Nokia Theater. There will be no funeral procession or outdoor viewing, and officials have encouraged people to watch from home.
