Singer and musician George Michael died at his home in Goring, England, on Sunday, the BBC reports, and his publicist confirmed the death. He was 53, and wasn’t ill. No cause was given, but the Thames Valley Police said the singer’s death “is being treated as unexplained but not suspicious.” Michael found fame with the duo Wham! in the early 1980s, alongside Michael’s school friend Andrew Ridgeley, and after a string of hits including “Careless Whisper,” “Freedom,” and the Christmas song “Last Christmas,” Michael broke out on his own with the hit albums Faith and Listen Without Prejudice Vol. 1. Born Georgios Panayiotou in north London, Michael came out as gay in the late 1990s, after an arrest for public indecency, and had trouble with drugs and driving under the influence over the past decade. There is a documentary about him, Freedom, coming out in March.
