Sir Elton John is reportedly slated to perform at his close friend George Michael’s funeral. The ex-Wham! singer was found dead on Christmas Day in his Oxfordshire, England, home.

While the funeral plans for Michael have not been confirmed, Metro reported that two ceremonies will be held — one for close friends and family and the other for his fans. Fellow pop icon John is likely to perform the pair’s 1991 duet "Don’t Let The Sun Go Down On Me." Earlier, reports claimed that Michael will be buried next to his mother Lesley Angold Panayiotou in Highgate Cemetery. She died from cancer in 1997.

“George’s love for his mother remained as strong as it had always been, and he always said he hoped he would be able to be with her again,” a source told the Sun. “George Michael’s family have a private plot where his mother is buried — and there is currently space within it for further burials.”

The news of Michael's untimely death came as shock to his longtime friend John. The 69-year-old singer posted a photo of the two together expressing his grief and offering condolence to Michael's close ones.

"I am in deep shock. I have lost a beloved friend — the kindest, most generous soul and a brilliant artist. My heart goes out to his family, friends and all of his fans. @GeorgeMichael #RIP," John wrote on an Instagram post.

Michael's body was discovered by his boyfriend, Fadi Fawaz, and according to the singer’s manager, he died from heart failure.

Following his death, many fans have wondered what will become of his fortune. Michael’s estate is valued at $125 million and could see up to $10 million more over the next two years, because of an increase in popularity for his music. 

According to a report in the Daily Mirror, Michael's fortune could be divided between his celebrity godchildren, including Martin Kemp's children Roman and Harley. Other godchildren who could also benefit from his fortune include James and Harry Kennedy, sons of Andros Georgiou — a close friend of Michael.
