Last Friday, Prince's family released a statement addressing speculation regarding Wednesday's ceremony and future memorial plans:

"Contrary to previous and current reports, there has been no memorial, funeral or tribute service for Prince that was organized or authorized by the family or Paisley Park representatives. Together, the family is planning an official memorial service and public event to take place in the near future. Prince and his music influenced so many people that we feel inspired to celebrate his life and legacy in just the right way. We appreciate the public’s patience and have been comforted by your outpouring of love, support and condolences. We look forward to sharing with the world this celebration of, and farewell to, our Prince. Details will be coming soon."

The statement was signed by Prince's sister, Tyka Nelson, and his five step-sibling, Alfred Jackson, John Nelson, Norrine Nelson, Omarr Baker and Sharon Nelson -- all of whom are possible inheritors to the musician's ample fortune.
