The ‘Wake Me Up Before You Go-Go’ pop sensation was a close friend and confident of the royal rebel after they formed a special bond at the 1989 World Aids Day concert at Wembley.

In David Nolan’s ‘George Michael: Freedom: The Ultimate Tribute 1963-2016’, it’s revealed that the pair could have dated.

The biography claims the former Wham singer said: “She was like a lot of women who have been attracted to me in my life.

“They see something non-threatening. There were certain things that happened that made it very clear that she was very attracted to me.

“There was no question."

According to the new book, the pair would sit up for hours on the phone discussing Diana’s divorce from Prince Charles.

The man behind hit single, Careless Whisper, is also said to have given a copy of an answering machine recording to Andros Georgiou, a close friend, in which the mother of William and Harry expressed how unhappy she was in her marriage to Charles.

Mr Georgiou said: “She often confided in him about how unhappy she was with Charles during their meetings.

“She told him their marriage had been an arranged one and that, as she’d been so young, she’d no real idea of what she was getting into.”

It’s also claimed Diana told him: “Not a very loving, compassionate family, this one I’m leaving.”

The royal princess used to invite Michael to Kensington Palace for a “chinwag” and is said to have hinted at her feelings towards him during their liaisons.

Mr Georgiou is quoted in the book as saying: “He said she made a point of touching his arm and her hello and goodbye hugs lingered.

“George told me, ‘Nothing happened, but it could have. If I wasn’t gay, I would’.”

Mr Georgiou has previously been quoted in the media saying that his friend was once offered a bed at the Princess Diana’s home.

He said in 2016: “They had a very honest friendship.

“On his third visit to Kensington Palace, they drank a bottle of wine tog­e­ther and George was so drunk she offered him a room for the night.

“This was about two years before she and Charles officially separated.”

When asked if he had ever considered sleeping with Diana, Michael is said to have replied: “I knew it would have been a disastrous thing to do.”
