George and Diana became close after meeting backstage at a concert in 1989, with the revelation being made in a 1996 phone call when George called to wish the Princess a happy birthday.
According to The Sun, the phone call was recorded by George’s answering machine and the singer then gave the tape to his friend, Andros Georgiou, who was with George when the conversation took place.
Confiding in her friend, Diana reportedly said of her divorce: “It’s been pretty grim, but we’re near the end of it.”
George then asked the royal if she thinks that she will “get what she has asked for”, with Diana replying: “I’m going to get three quarters of what I want and the quarter he can’t have, so there you go.
“Not a very loving, compassionate family, this one I’m leaving, I tell you.”
The pair then shared jokes about an Elton John documentary that George had appeared in, with the friends quipping about how extravagant Sir Elton’s life is and Diana comparing the music icon to Imelda Marcos.
The recorded conversation ends with George telling Diana that he would “love to see” her, with Diana replying that she’d prefer to “wait until things quieten down”.
Speaking of George and Diana’s “honest” friendship, George’s childhood friend Andros said: “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.”
Princess Diana sadly passed away in August 1997, with George being found dead in his bed on Christmas Day, 2016.
