PRINCESS Diana was told to wear a wig so she would look like rival Camilla to spice up her sexless marriage with Prince Charles by pals. 

A new book by  Royal biographer and The Crown historian Robert Lacey reveals she would joke with friends about getting no action.

Diana is reported to have said she wanted to get the future king drunk to make him have sex with her.

Robert’s book says: “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’.

“‘Oh no’, they would respond, ‘You know what happens to the vital organ under the influence of too much alcohol – brewer’s droop’. ‘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.”
