Michael Jackson Burial Date Still Uncertain, Joe Jackson Says

Family reportedly needs more time to prepare for ceremony.

Earlier this week, a spokesperson for the Jackson family confirmed that Michael Jackson would be buried on August 29 — the day that would have been the late singer's 51st birthday. But it now appears that the family needs more time to prepare and will have to postpone the ceremony.

Initial reports suggested that the new date would be two days later, on August 31, but Joe Jackson told E! News that he still doesn't know when the burial will take place. "We have to figure it out," he said.

The ceremony will still happen at Forest Lawn Memorial Park in Glendale, California, and the family has agreed to a request from the Glendale Police Department that asked the Jackson family to foot the city's entire bill for the event, which includes money for police officers and additional security personnel.

Jackson's burial won't be the end of the tributes to the legend, who passed away on June 25. Tickets went on sale Thursday for the Jermaine Jackson-produced tribute concert in Vienna, Austria, on September 26. Though that concert still doesn't have a lineup, its official Web site crashed after more than a million people reportedly tried to buy tickets.

And on October 28, the Kenny Ortega-directed film "This Is It," a documentary made up mostly of rehearsals for Jackson's planned residency at London's O2 arena, will hit theaters for two weeks only. Tickets for the movie go on sale on September 27.
