UPDATE: Yoko Ono has posted a statement on her website:
Cynthia Lennon, John Lennon’s first wife and the mother of Julian Lennon, has died at 75. She suffered from cancer.
Lennon’s representative provided the following statement:
Cynthia met and married John in 1962, when she was 18. One year her junior, John was poised for stardom as a part of The Beatles. In 1963 the Lennons had their only son, Julian, and after a brief and rocky marriage they divorced in 1968, after Cynthia learned John had impregnated Yoko Ono—whom he married the following year.
Cythnia would later write two books about her life with the Beatle: 1980’s A Twist of Lennon and 2005’s John.
