It has also been reported that his close friend Geri Horner will give a reading at the funeral.
The Sun also exclusively revealed George has left his £10million London mansion to his favourite older sister Melanie Panayiotou , 55, who has already moved into the Highgate home as she organises his funeral.

George Michael with beloved mum Lesley Meanwhile, his cousin Andros Georgiou exclusively told the Sun On Sunday how there won't be a traditional Greek Orthodox ceremony which his family had been hoping for.
He explained: “For that to happen, he needed to be buried in a Greek Orthodox cemetery, and it was very clear in his wishes that he wanted to be with his mother.
“She - and his first love Anselmo Feleppa - were the real loves of his life.
“His family were disappointed, but they are relieved they can finally lay him to rest. I don’t believe you can really grieve until you have buried someone. I believe everything is ready for the funeral, but it is now about security.
“There are already fans lining up outside Highgate Cemetery, and much as he loved his fans, his family don’t want his funeral to turn into a circus.
“I would ask those fans to pay their respects by allowing them to bury him in peace.”
Meanwhile, Andros also told The Sun how George's lover Fadi Fawaz has "snubbed" the superstar's family since his tragic death.
The 43-year-old has made no attempt to get in touch with the singer’s dad and sisters , his cousin Andros Georgiou said.

Andros spoke days after an inquest ruled the Careless Whisper singer died of natural causes – but did not reveal if drink or drugs were in his body.
Coroner Darren Salter said he died from heart and liver problems.
But his short statement made no mention of the long-awaited results of a second toxicology test, after the first returned an “inconclusive” verdict.
And Andros — the chart-topper’s closest childhood friend — said results were withheld after his family begged the coroner to keep them private .
He went on: “George’s dad has read the results, but they are still too difficult for him to talk about. He is very upset, and just wants to lay his son to rest."
Andros — who was not biologically related to George but was called his “cousin” as they were so close — continued: “The news he died of natural causes was a relief."
He also revealed George's last music will not be released posthumously.
