Pop superstar George Michael's death at the age of 53 from suspected heart failure is being treated by UK 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 on Christmas Day, his publicist said.
The cause of the star's death was heart failure, according to his manager Michael Lippman.
Lippman said Michael was found "in bed, lying peacefully".
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 family would ask that their privacy be respected at this difficult and emotional time. There will be no further comment at this stage."
The 53-year-old, who was set to release a documentary in 2017, rose to fame as a member of Wham!, known for their hits Club Tropicana and Last Christmas.
Michael - whose real name is Georgios Kyriacos Panayiotou - sold more than 100 million albums throughout a career spanning almost four decades.
Health scares dogged the last decade of Michael's life. Last year he publicly denied new allegations about drug-taking, describing them as "highly inaccurate".
The star nearly died from pneumonia in late 2011. After receiving treatment in a Vienna hospital, Michael made a tearful appearance outside his London home just before Christmas and said it had been "touch and go" whether he lived.
In 2013 Michael had to be airlifted to hospital with a head injury after falling from his vehicle on the M1 near St Albans in Hertfordshire.

Doctors had performed a tracheotomy to keep his airways open and he was unconscious for some of his spell in hospital.
Meanwhile, Michael's 1990 album "Listen Without Prejudice Vol.1" had been set to be reissued accompanied by a new film featuring Stevie Wonder, Elton John and the supermodels who starred in the video to his hit single Freedom! '90.
The movie, with the working title Freedom: George Michael, was to be narrated by Michael and set to feature Mark Ronson, Mary J Blige, Tony Bennett, Liam Gallagher, James Corden and Ricky Gervais.
The record was his second solo album, after the hugely successful Faith, and was arranged produced and almost entirely written by Michael, but did not feature him on the album cover.
Tributes from stars including Martin Fry and Ricky Gervais, who included Michael in an episode of his sitcom Extras, poured in on Twitter.
Elton John also took to Instagram to convey his sadness, saying he was in "deep shock".
The pair famously collaborated on a rendition of Elton's classic "Don't Let The Sun Go Down On Me", released in 1992, nearly two decades after the original.
