Sir Paul McCartney is said to be furious after a new book he contributed to accuses John Lennon of wanting a gay relationship with his fellow beatle.
MCCartney and Lennon's widow Yoko Ono, 75, both reportedly agreed to be interviewed for author Philip Norman's new biography, John Lennon: The Life.
But after learning the book claims Lennon lusted over MCCartney and fantasised about his mother, the pair are allegedly distancing themselves from the project, with Ono withdrawing her endorsement.
A source tells Britain's Daily Mirror, "Both Sir Paul and Yoko are extremely angry and upset."
