A tweet from UK television presenter Richard Osman has been retweeted over 34,000 times after alleging the late singer donated £15,000 ($25,000) to a woman who appeared on Deal or No Deal, attempting to win that amount of money to fund her IVF treatment.

Osman, who worked as an executive producer on the game show, said the singer "secretly phoned" the next day to gift the woman the money.

Although Osman did not reveal the identity of the woman, a woman named Lynette Gillard, from Bolton, England, saw the tweet and claimed to be the recipient.

The 38-year-old told the London Telegraph she received £9,000 from an anonymous donor after her then-husband appeared on a 2008 episode of Deal or No Deal but won less than the total amount needed for a round of IVF.

"For many years I wondered who would of been so generous and now I know," Gillard said. "What more can I say other than thank you George."

A spokesman for the game show would not confirm the donor's identity to the Telegraph.

Osman's story seemingly prompted others to report random acts of kindness and charity work the late singer performed anonymously.

One Twitter user said the singer worked at a homeless shelter, and asked his fellow volunteers to not tell anyone. Another said he saw him give a waitress a cheque for £25,000 ($43,000) to give to a woman who had been crying about her debt at the cafe after he had left.

The stories have not been confirmed.

In addition to his iconic music career, George Michael is being remembered for his philanthropy.

He was a dedicated supporter of AIDS sufferers charity the Terrence Higgins Trust, as well as UK confidential youth counselling service, Childline.

Fellow musician Billy Bragg reminded his Twitter followers on Boxing Day that the singer played free concerts open to any nurse working in the UK's National Health Service to express his gratitude to those who looked after his late mother during her cancer battle.
