George Michael has reportedly split with his partner Kenny Goss after 13 years. Goss is said to have walked out on the singer at Christmas, just three months after the Michael was arrested in a toilet on London's Hampstead Heath, but the pair tried to keep their relationship split a secret, according to Britain's Daily Mirror.

A source tells the publication, "Kenny had given George many chances. But after the Hampstead Heath incident he said he couldn't take any more. Everyone knew George wasn't just in there to do drugs - the place is well known as a place to pick up men. Despite George saying they had an open relationship, Kenny never agreed with George's urges to go out cruising for other men, or with his excessive use of cannabis. He is embarrassed by what George had put him through. They had been due to marry on their 10th anniversary back in 2006, but Kenny told him it was off unless he changed his ways. But it seems George just couldn't."

The publication alleges the Wham! star spiraled into a deep depression following the break-up, worrying friends with his reclusive and erratic behavior. And the star is said to have sunk even lower after firing his manager Andy Stephens in June following an argument over his surprise duet with Beyonce at a concert in London.

A pal adds, "When Kenny left him, George wasn't in the right frame of mind for anything. He seemed to become really depressed and no one could talk him out of it... "

"His manager Andy couldn't get through to him. And then he was absolutely furious when he found out he had driven himself to the O2 Arena and got on stage with Beyonce. He tried to confront the star about it but George sacked (dismissed) him."
