Michael shot to fame with the 1980s band Wham! and sold over 100 million albums in his career, winning two Grammys and three Brit awards.

Referring to him by his nickname "Yog" (Yours Only George), WHAM! co-star Andrew Ridgeley said he was "heartbroken" by Michael's death.

Many reactions referred to the spate of music world deaths in 2016, starting with David Bowie in January.

Singers Prince and Leonard Cohen also died this year and Status Quo guitarist Rick Parfitt passed away on Saturday in a Spanish hospital.

"2016 - loss of another talented soul. All our love and sympathy to George Michael's family," the band Duran Duran, who were 1980s contemporaries of WHAM!, said on their official Twitter account.

Spandau Ballet, a British band which formed in the late 1970s, wrote: "We are incredibly sad at the passing of our dear friend George Michael. A brilliant artist & great songwriter."

Newer pop stars also paid tribute to the influential London-born artist, who was planning to release a new album and a documentary next year.

"Oh God no... I love you George... Rest in peace," wrote pop star Robbie Williams, while fellow singer Pixie Lott paid tribute on Twitter to the "beautiful and talented" Michael.

In the United States, Recording Academy president Neil Portnow said he was "deeply saddened" by the loss.

"During an influential career that spanned nearly four decades, George became one of the most beloved pop craftsmen and respected entertainers," said Portnow, whose organisation awards the Grammys.

"From the enormous success he achieved with pop duo Wham! to his influential solo career, his extraordinary talent had a profound impact on countless entertainers worldwide, and his creative contributions will live on forever," he said.

Canadian musician Bryan Adams tweeted: "I can't believe it. Such an incredible singer and a lovely human being, far too young to leave us."

US singer La Toya Jackson wrote: "You have given the world an amazing gift! What a talent! What a loss!".

The gay rights charity Stonewall said: "You inspired many and your music will live on in the hearts of the community. You will be sorely missed."
