George Michael, the creamy-voiced English songwriter who sold tens of millions of albums as a member of the duo Wham! and on his own, was found dead on Sunday at his home in Goring in Oxfordshire, England. He was 53.

A police statement said: “Thames Valley Police were called to a property in Goring-on-Thames shortly before 2 p.m. Christmas Day. 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.”

Mr. Michael’s manager, Michael Lippman, told The Hollywood Reporter that Mr. Michael had died of heart failure “in bed, lying peacefully.”

“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,” his publicist Connie Filippello said in a statement. “The family would ask that their privacy be respected at this difficult and emotional time. There will be no further comment at this stage.”
