Pop superstar George Michael's death at the age of 53 from suspected heart failure is being treated by police as "unexplained but not suspicious".
The 53-year-old, who rose to fame as the front man of Wham! and had chart-topping hits including Last Christmas, died peacefully at home, his publicist said.
The cause of the star's death was heart failure, according to his manager Michael Lippman.
Big names from the world of entertainment have paid tribute to him after hearing about his death, which comes in a year that has seen the music industry lose some of its biggest stars including Prince, David Bowie and Leonard Cohen.
Sir Elton John posted a photograph of himself and Michael on Instagram, writing: "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 and all of his fans."
Michael's former Wham! bandmate Andrew Ridgeley said he was "heartbroken at the loss of my beloved friend Yog", a nickname which refers to "Yours Only George".
He said: "Me, his loved ones, his friends, the world of music, the world at large. 4ever loved. A xx"
Friend Madonna paid her own tribute, posting an undated video on Twitter in which she embraced Michael on stage. In it she tells the audience: "He's a great songwriter and he makes very classy videos, like me."
Referencing several of his best known lyrics, she adds: "George, I want your sex, so be my father figure and I will have faith if we have to live hand-to-mouth. The diva himself."
On Sunday night, Thames Valley Police said they were called to a property in Goring-on-Thames shortly before 2pm, adding: "Sadly, a 53-year-old man was confirmed deceased at the scene.
"At this stage the death is being treated as unexplained but not suspicious. A post-mortem will be undertaken in due course. There will be no further updates from Thames Valley Police until the post-mortem has taken place."
The star's publicist said: "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.
"The family would ask that their privacy be respected at this difficult and emotional time. There will be no further comment at this stage."
