Musicians, politicans and actors alike are mourning the death of British musician George Michael.
Michael, who launched his career with duo Wham in the 1980s and later continued his success as a solo performer, is said to have "passed away peacefully at home", early on Christmas afternoon (GMT).
Police have said they are treating the death as unexplained but there were no suspicious circumstances.
Musicians and others were quick to take to social media to voice their disbelief.
The other half of Wham, Andrew Ridgeley, said on Twitter he was "heartbroken" at Michael's death.
"I am in deep shock," said Elton John. "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. @GeorgeMichael #RIP."
Fellow 80s superstars Duran Duran also tweeted their condolences.
Referencing some of Michael's biggest hits, Star Trek actor and LGBT rights activist George Takei said: "Rest with the glittering stars, George Michael. You've found your Freedom, your Faith. It was your Last Christmas, and we shall miss you."
Ellen DeGeneres and actor Ryan Reynolds were among others to pay their own tributes.
Ricky Gervais' writing partner Stephen Merchant recalled Michael's appearance on the Christmas special of their comedy series, Extras.
Even UK Labour Party leader Jeremy Corbyn expressed his sadness.
"Sad to hear that George Michael has died. He was an exceptional artist and a strong supporter of LGBT and workers' rights."
In New Zealand, local fans were also taken aback by the news.
