London, October 24 The first wife of John Lennon, Cynthia, has criticised Paul McCartney for divorcing Heather Mills, calling him "stupid".

Cynthia, 70, whose son Julian was six when the Beatle dumped her for Yoko Ono in 1968, spoke for the first time about the much publicised 24.3million pound divorce.

"She (Heather) became the she-devil and he was stupid," the Daily Express quoted her as telling The Lady magazine.

"Like me, I think he should have given it more time. He got married and it was fabulous and then the chemistry wasn't right.

"But you have to be living with somebody long enough to know that the chemistry is right or not," she added. (ANI)
