Mariah Carey and Alicia Keyes are now linked to performances at the public memorial service.

Among the rumored performers is Diana Ross, who may wind perform at the start of the ceremony.

Stevie Wonder, Justin Timberlake and Jennifer Hudson will perform, according to numerous reports.

Elizabeth Taylor reportedly will read the eulogy, and other guests may include Whitney Houston, Beyoncé, Jay-Z, Lionel Richie, Liza Minnelli and Aretha Franklin.

More than 1.6 million fans tried to get 17,500 tickets to the memorial. Los Angeles police expect a crowd of 750,000 people near the site.

The two-day registration period for the service at Staples Center in downtown Los Angeles ended Saturday.

Listings on eBay for tickets started at $20,000 before eBay blocked the listings.

But Ticketmaster took several measures to prevent ticket-scalping.

City officials are preparing for massive crowds. Assistant Police Chief Earl Paysinger says anywhere from a quarter-million to 700,000 people may try to reach the arena, even though a wide area around Staples Center will be sealed off to those without tickets.

City Councilwoman Jan Perry strongly urged people to stay home and watch the memorial on TV. The ceremony will not be shown on Staples' giant outdoor TV screen and there will be no funeral procession through the city.

No details were given about the actual memorial events, which come as the nation's second-largest city struggles with a $530 million budget deficit. Perry said the cost of police protection for "extraordinary" events like the memorial is built into the Police Department's budget, but she still solicited help for "incremental costs."

Last month, donations covered about $850,000 of the city's $1 million cost for the Los Angeles Lakers' NBA championship parade. Critics had blasted the idea of using city money when it is considering layoffs to close its budget gap.

More than 1.6 million fans signed up online for 18,000 tickets for the Michael Jackson service on Tuesday.

The memorial will be broadcast live at 1 p.m. ET Tuesday on MyFoxPhilly.com.
