Michael Jackson is shown rehearsing at the Staples Center on June 23, two days before his death.
Jackson's family will hold a private ceremony before the public memorial service, his brother said Thursday.
Speaking to CNN's Larry King, Jermaine Jackson said the ceremony will be held Tuesday morning, but he did not say where.
Jackson rehearsed at Staples Center two nights before he died, and he appeared healthy in a video clip of the rehearsal obtained by CNN. Jackson died June 25 after collapsing at his rented home in Los Angeles.
AEG, promoter of Jackson's planned London, England, shows, released the short video of Jackson rehearsing in the arena on June 23.
