George Michael's family is going through another tragedy.
On Christmas Day, the three-year anniversary of Michael's death, the singer's younger sister, Melanie Panayiotou, died, ET can confirm.
The Metropolitan Police tell ET that they were called by London Ambulance Service at approximately 7:35 p.m. on Wednesday to reports of the sudden death of a woman in her 50s at an address in Oak Hill Park. The death is not being treated as suspicious by police. A report will be compiled for the Coroner into the circumstances.
John Reid, the family attorney, tells ET that the family has asked him to issue the following statement: "We can confirm that very tragically Melanie has passed away suddenly. We would simply ask that the family’s privacy be respected at this very sad time. There will be no further comment."
On Christmas Day in 2016, Michael died at age 53 of heart failure in his sleep at his country home in London.
"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 rep told ET at the time. "The family would ask that their privacy be respected at this difficult and emotional time. There will be no further comment at this stage."
