George Michael's boyfriend is said to have checked out of an Arizona clinic where he was being treated for alcohol addiction.
Kenny Goss agreed to get help after George pleaded with him to get treatment.
A close friend of the celebrity couple told the News of the World that, "George was one of the people who encouraged Kenny to seek help.
"His drinking got out of control and Kenny realised he had to sort it out.
"It was a tough time for them but because of the strength of their relationship, they have managed to stay together."
Kenny has now checked out of the clinic and will fly back to Britain to be reunited with George, who has supported him throughout his two-month treatment.
There have been rumours suggesting that Kenny was actually fighting drug but sources told the paper that, "It is nothing to do with drugs. It was alcohol that was the problem."
Earlier this year George revealed that he regularly had sex outside of his eight-year relationship with Kenny.
"Neither of us practises monogamy. Well, if one of you does, it's really sad, isn't it? And yes, it works,” George told the Daily Mirror.
"There's no getting to know someone that you're sleeping with. There's no dining, there's no going about the social graces, whatever. You have people on the side when you need sex. Simple as that," he added.
The singer said that he always practised safe sex and claims the couple's sexual encounters with others do not harm the relationship.
"No jealousy. After eight years, I can walk out the door and tell him I'm off to get my end away. And there's not a piece of him that worries. And vice versa.
"We had our couple of years of that bliss, and we have to mix that up with the desire for newness, with the desire for the unknown. Which is what drives men's sexuality."
In 1998 George was famously outed when he was caught propositioning a policeman in a Los Angeles toilet.
