George Michael was found dead at his home in Goring-on-Thames on Christmas Day in 2016 aged 53.
In March the following year, a coroner confirmed the singer had died from natural causes as a result of heart and liver disease.
Fadi Fawaz, George’s partner at the time, said he found the singer “lying peacefully in bed”.
Now, Andrew Ridgeley, 56, has spoken out about his friend’s death in his new book Wham! George & Me.
The singer admitted he was still “unclear” about the circumstances surrounding George’s passing.
According to The Mirror, he wrote: “The circumstances of his death seemed unclear, only compounded the distress.
“Without any real closure, the grieving seemed terribly raw.”
Despite a heart condition being recorded as George’s cause of death, Andrew added: “There were still a number of questions.
“He seemed to be in good health and there are conflicting reports surrounding the night [before] his passing.
At the time, Fadi said he found George dead in his bed after claiming they slept separately following a dispute the night before.
Andrew added: “When someone dies alone, perhaps there are always answers that remain out of reach. It still feels uncomfortable, though.”
Elsewhere in his book, Andrew said he feared George would die with AIDS, according to The Sun.
The singer recalled the moment his band mate opened up to him and Shirlie Holliman about his sexuality in 1983.
He said: “When I walked across the hallway to George’s room, Shirlie was already there, perched on a large sofa in the suite.
“George was still in bed. He smiled as I came in.
“The mood in the room was so relaxed and familiar, yet what George was about to reveal was clearly a big deal for him.
“‘I didn’t know whether to tell you this’, he said, looking across at Shirlie. ‘But I’m going to. I’m gay’.”
At the time of George coming out, concerns about AIDS were widespread.
“A terrible additional worry was the emergence of Aids,” he added.
“I know I wasn’t the only friend of George’s who worried about him during that uncertain, frightening period.”
