George Michael's former partner has said he thinks the Wham! star's body "just gave up" when he died.
Kenny Goss said the singer, who suffered from health scares and years of drug addiction, was "just weak".
The 58-year-old American art dealer, who had a relationship with Michael for 15 years, told the Sunday Mirror that his family and friends now just want to lay him to rest.
He said: "We just want closure, we want the funeral to happen, it's been a long time now."
Michael was found dead aged 53 at his home in Goring-on-Thames, Oxfordshire, on Christmas Day but the cause has not yet been made public.
Further tests were needed after a post-mortem was inconclusive and it is understood Michael's body remains with the coroner.
Goss said: "I can't say for sure but I think his body just gave up.
"All these years, it was just weak."
There is speculation that Michael, who rose to fame as the front man of Wham! and had chart-topping hits including Last Christmas and Freedom, died of heart failure.
Thames Valley Police said there were no suspicious circumstances surrounding the death.
Goss and Michael split in 2009, although the star did not reveal the break-up until 2011.
During their relationship the pair started the Goss-Michael Foundation, which provides support for community and educational arts programmes.
Following the singer's death Goss said he had been left "heartbroken with the news that my dear friend and long-time love George Michael has passed".
