JOAN RIVERS, the sassy, sharp-tongued comedy legend who jokingly wrote about wanting an elaborate funeral, was to be laid to rest in a private service Sunday.

    The New York City Medical Examiner’s Office said Friday that after an initial examination, further tests were needed to determine the cause of Rivers’ death.

    The comedian passed away in a New York hospital Thursday, a week after she stopped breathing during an outpatient procedure at a clinic and suffered cardiac arrest.

    Rivers, 81, was to have an invitation-only funeral at Temple Emanu-El, a landmark synagogue on New York’s Fifth Avenue where she was a member of the congregation.

    “We mourn with her family, friends and all those millions to whom she brought laughter and joy,” Senior Rabbi Joshua M. Davidson, who will conduct the service, said in a statement.

    No details of the service were released, but in her 2012 book “I Hate Everyone ...Starting With Me,” the comedy star wrote about wanting her funeral to be a big show biz affair, complete with actress Meryl Streep crying in different accents.

    The future of Rivers’ E! cable television show “Fashion Police,” which comments on the unfortunate red carpet choices of Hollywood celebrities, is uncertain.

    The program was initially scheduled to miss two weeks following Rivers’ hospitalization.

    Rivers’ death was the second of a famed U.S. comedian in less than a month. Comedy genius and actor Robin Williams, 63, hanged himself in California on Aug. 11.

    Rivers’ influence reached far beyond her New York roots. Her blunt, unapologetic humor made millions of people around the globe laugh.(SD-Agencies)
