The post-mortem examination on George Michael's death has been ruled "inconclusive," Breaking Celebrity News has learned.

As Breaking Celebrity News readers know, the 53-year-old was found dead by boyfriend Fadi Fawaz on December 25 at his Oxfordshire residence in England.

Michael’s rep confirmed the news earlier this week in a statement that read: "It is with great sadness that we can confirm our beloved son, brother and friend George passed away peacefully at home over the Christmas period."

Meanwhile, a source revealed that the Wham! rocker was battling a secret heroin addiction in the months before his death, claiming the famed rocker was even treated in the hospital for an overdose earlier this year.

"He's been rushed to A&E on several occasions," said the insider. "He used heroin. I think it’s amazing he’s lasted as long as he has."

Following Michael's shocking passing, it was revealed that the singer's sisters will receive the majority of his fortune.
