Pop superstar George Michael died yesterday, Christmas Day, at the age of 53.

“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,” reads a statement from his publicist, Michael Lippman. “The family would ask that their privacy be respected at this difficult and emotional time. There will be no further comment at this stage.”

George Michael rose to fame as one half of 80’s pop group Wham! and went on to have a successful solo career. Over the course of his almost 40-year career, he sold more than 100M albums worldwide.

Stars took to social media on Sunday to pay tribute to the late star.

Paul on George Michael: “George Michael’s sweet soul music will live on even after his sudden death. Having worked with him on a number of occasions his great talent always shone through and his self deprecating sense of humour made the experience even more pleasurable.” — Photo by Mike McCartney, LIVE 8, July 2005 #PaulMcCartney #GeorgeMichael ​
