Singer George Michael has split up with his long-term partner Kenny Goss.

Goss, 50, reportedly walked out on the star at Christmas but the split has been kept secret until now.

The couple had been together for 13 years but Goss was said to have become sick of Michael’s behaviour.

According to reports, the final straw came when Michael, 46, was arrested in public toilets on Hampstead Heath and charged with drug possession last year.

Friends said the former Wham! singer had been holed up in his Highgate mansion all year smoking cannabis and playing computer games.

One said: “Kenny had given George many chances. But after the Hampstead Heath incident he said he couldn’t take any more. Kenny never agreed with George’s urges to cruise for other men, or with his excessive use of cannabis.”
