Whitney Houston Death Certificate

Whitney Houston’s official death certificate has been filed in L.A. County — and according to the document the cause of death is still undetermined.

The manner of death is listed as “pending investigation” — and the immediate cause of death is “deferred.”

Whitney’s occupation is listed on the document as an “entertainer” who worked in the industry for 33 years — beginning when she was just 15.

According to the document, Whitney will be laid to rest on Saturday at the Fairview Cemetery in Westfield, NJ — the same cemetery where her father is buried.

As we previously reported, the L.A. County Coroner’s office is awaiting toxicology results in order to determine an official cause of death — a process that typically takes 4-6 weeks. The autopsy was completed Sunday.
