'Celeb' Rehabber Mike Starr -- Funeral Plans on Hold

Ex-Alice In Chains bassist Mike Starr won't be getting a funeral for another few weeks -- we're told, the medical examiner put the family's burial plans on hold ... in order to perform more tests on Mike's body.

No word yet on what tests still need to be done ... but Mike's family ain't waiting around -- we're told they're holding a memorial without Mike's body this Sunday in Seattle for friends and family ... to give them a chance to pay their respects early.

Once Mike's body is back in the family's possession, sources tell us, they plan to hold TWO funeral services -- one for fans, and one for family.

As we previously reported, Mike died suddenly last week in a Salt Lake City home -- after mixing methadone and anxiety pills.
