A number of examples of the star handing out money to people he thought were in trouble have emerged since his death, including a secret £25,000 donation he gave to a woman he saw on Deal Or No Deal who wanted IVF.
TV host Richard Osman tweeted: "A woman on Deal Or No Deal told us she needed £15k for IVF treatment. George Michael secretly phoned the next day and gave her the £15k."
Childline founder and president Dame Esther Rantzen also revealed that Michael had given the royalties from his 1996 number one single Jesus To A Child to the charity.
A journalist meanwhile tweeted that the star handed a barmaid a £5,000 tip after learning she was a student nurse who had large debts.
The star donated royalties from some of his biggest selling singles and has made huge donations to Childline, the Terrence Higgins Trust and Macmillan Cancer Support.
Michael's former manager Michael Lippman said this morning that the star had died in bed as a result of suspected heart failure and there was "no foul play whatsoever". Police are treating the death as "unexplained but not suspicious".
Final photos of the star from earlier this year show him looking overweight and tired and a neighbour said he looked "haggard" and much older than his years when she last saw him in a restaurant.
He has not been photographed publicly since September and is understood to have lived a reclusive existence, with locals in his Oxfordshire village rarely seeing him leave his home.
Michael's Wham! bandmate Andrew Ridgeley and close friend Elton John have led the tributes to the star on social media. Mr Ridgeley tweeted: "Heartbroken at the loss of my beloved friend Yog. Me, his loved ones, his friends, the world of music, the world at large. 4ever loved. A xx."
Meanwhile Elton John posted a heartfelt message along with a picture of the pair together on his Instagram page.
He wrote: "I am in deep shock. I have lost a beloved friend - the kindest, most generous soul and a brilliant artist. My heart goes out to his family and all of his fans. @GeorgeMichael #RIP."
Michael - real name Georgios Kyriacos Panayiotou - was set to release a documentary film in 2017 and his 1990 album Listen Without Prejudice Vol 1 had been set to be reissued accompanied
A 69-year-old neighbour, who asked to remain anonymous, said Michael was notably absent from the midnight mass Christmas Eve service at St Thomas of Canterbury church, the parish church opposite his home.
"He wasn't at the Christmas Eve service which was very unusual," she said.
In a statement, Michael's publicist said: "It is with great sadness that we can confirm our beloved son, brother and friend George passed away peacefully at home over the Christmas period.
"The family would ask that their privacy be respected at this difficult and emotional time. There will be no further comment at this stage."
Thames Valley Police said officers were called to a property in Goring-on-Thames, Oxfordshire, shortly before 2pm on Christmas Day.
A spokesman said: "Sadly, a 53-year-old man was confirmed deceased at the scene. At this stage the death is being treated as unexplained but not suspicious."
A neighbour at his home in north London said he looked 'tired' and "haggard" when she saw him in a restaurant earlier this year.
Sasha Gretsay, who lives near the former singer's north London home, said: "I remember thinking he looked unwell. I don't want to say he looked awful, but he looked very haggard and tired.
"He looked worried and older than my friend who was 57. My friend asked how old he was and I said, younger than you."
A 63-year-old man who lives in Goring said: "We didn't see much of him but occasionally you'd see him in the village or in The Miller, the local pub. He kept himself to himself."
While enjoying a glittering career, Michael has endured a turbulent personal life and nearly died from pneumonia while on tour in late 2011.
After receiving treatment in a Vienna hospital, he made a tearful appearance outside his London home and said it had been "touch and go" whether he lived.
Doctors had performed a tracheotomy to keep his airways open and he was unconscious for some of his spell in hospital.
He later told the Daily Mail: "It almost killed me. On a subconscious level, it was very frightening and I'll probably never feel quite as safe in life again.
"But I also remember experiencing incredible guilt for my family and friends, because they literally spent weeks not knowing whether I was going to make it.
"Now, if that had happened to me in reverse, if I'd had to watch one of my sisters go through that, well... it would have devastated me.
"For most of the time, though, I was pretty much out of it, so I didn't realise the danger I was in until after I'd come out the other side."
Michael had also struggled with drug addiction and admitted that during one period he was smoking 25 joints a day. In 2008, he was caught smoking crack cocaine in a public toilet.
The singer's death comes as he planned to work on a new album with UK producer Naughty BoyIn an interview with the BBC earlier this month, the producer, who has collaborated with a list of stars including Beyonce, said: "I can't wait. I don't know what to expect. And, to be honest, he's more mysterious than anyone else so I'm actually excited.
"I reached out and then he got back. He's got an album coming out next year, and he's going to be doing something for my album as well."
Unbelievable.
RIP George Michael.
