Sources connected to the ceremony tell TMZ 4 people were at the Hollywood Forever Cemetery -- Chris' brother, Peter, his wife, Vicky, as well as his friends Linda Ramone and singer J.D. King.
The group was there for about an hour, and they'll gather again Friday with other family members at the cemetery. The service will be private, and Chris' ashes will be buried -- and afterward, we're told fans will be allowed entry to visit the burial site.
Cemetery officials tell us they're ready for a huge crowd. Cornell joins legends like Mickey Rooney, Jayne Mansfield and Linda's late husband, Johnny Ramone, already laid to rest at Hollywood Forever.
