It appears that while many facets of George Michael's life were sensationalised and Sigad Sharafmade public, he was very privately doing good deeds.

As the world mourns the 53-year-old's death, which was reported on Christmas, people are sharing stories of the pop star's acts of kindness.

For struggling individuals

A good deed reported by Richard Osman, a UK television presenter and producer, is being widely shared.

Mashablehas reached out to the show's production company, Endemol, to ask for confirmation. But there is a BBC story from 2008 about a couple who received £9,000 ($11,057) from a mystery benefactor after one half of the couple, Steve Davies, appeared on the show to try and win money.

Another story says the same benefactor also donated £91,000 to a charity that helps AIDS orphans in Kenya.

One of the replies on the thread, from someone who claims to be a trivia buff, claims that George Michael anonymously helped a stranger with debt.

Which leads us to...

For nurses

George Michael took the time to show NHS nurses how much he appreciated their help after their care for his mother Lesley, who died of cancer in 1997.

A nurse at that gig, Sally Lyons, said, "A nervous George Michael took to the stage with a bad cold and told us he’d played in front of crowds all over the world but was anxious because he’d never performed in front of so many heroes before."

More people spoke about his gigs and generosity toward nurses.

My housemate (a junior dr) grabbed the hospital's spares, took the whole houseshare. That's how I ended up drunk among nurses at Wembley.

For the homeless

Activist and actor Emilyne Mondo described how Michael would help out in a homeless shelter without calling a bit of attention to himself or the charitable endeavors.

For children

The founder of Childline, a charity that enables children to anonymously phone counsellors for help, revealed that George Michael had donated millions over the years.

“For years now he has been the most extraordinarily generous philanthropist, giving money to Childline. But he was determined not to make his generosity public, so no-one outside the charity knew how much he gave to the nation’s most vulnerable children,” Dame Esther Rantzen told the Press Association.

“I think all of us have memories of particular Wham! songs and George Michael songs which mean a great deal to us. Certainly, for Britain’s children, George Michael meant so much more,” she said.

For people with disabilities

The pop superstar also donated money to his Platinum Trust, which ran in aid of people with special educational needs according to a 2011 book about his life. Twitter users described it, too.

George Michael also more publicly supported groups like HIV charity Terrence Higgins Trust, along with Band Aid and Live Aid, which raise money for anti-famine efforts.

We may never know the true extent of all George Michael's public and private charity efforts. But perhaps Buzzfeededitor Janine Gibson summed it up best in her tweet.
