Princess Diana was reportedly told to wear a wig so that she looked like Camilla, in a bid to spice up her sexless marriage with Prince Charles
The claims have been made by royal biographer and The Crown historian Robert Lacey in a new book, as he takes a look into the relationship between the couple.
Lacey has claimed that Diana would look to get Charles drunk in the hope that he would want to take her to bed.
He has said that Diana used to joke with her friends that this was one of the only ways she could get some action in the bedroom.
In the book, Lacey writes: “Diana would both bemoan and joke about the bedroom boycott with her girlfriends.
“Perhaps she should try to get Charles drunk one evening, she suggested, in the hope of encouraging a bit of princely ‘leg-over’”.
Charles and Diana were married at St Paul’s Cathedral in 1981 and had two sons, William and Harry, but it wasn’t long before their physical relationship became almost non-existent.
In the book, Lacey continued to reveal details about the lengths Diana would go to get some love in the bedroom.
When saying that she would look to get him drunk, her friends would say: “You know what happens to the vital organ under the influence of too much alcohol – brewer’s droop.”
Lacey wrote: “‘How about turning down the lights and wearing a blonde wig?’ asked one of them. ‘That way he might mistake you for Camilla.’
“Diana roared with laughter. After time and some rueful reflection, she had come to accept the reality of her husband’s ‘lady’ in his life.”
Charles and Diana saw their marriage descend into a series of allegations about the future king having an affair with Camilla, before they finally divorced in 1996.
Diana famously said in a 1995 interview with the BBC: “Well, there were three of us in this marriage, so it was a bit crowded.”
Diana had previously opened up about her sex life when she had sessions with speech coach Peter Settelen.
During the sessions in 1992 and 1993, Diana described as their attempts in the bed as “very odd”.
She said: “Well, there was [sex]. There was. There was. But it was odd, very odd.
“But it was there then it fizzled out about seven years ago, six years ago, well seven, because Harry was eight.”
