In 1982, Cher was starring in Broadway show Come Back to the Five and Dime, Jimmy Dean, Jimmy Dean when she noticed a man waiting for her at the stage door.
She figured he would give her a handshake.
"I thought he was going to shake my hand, and he grabbed my arm and put it behind my back," she told The Guardian.
Watch: The wildest Met Gala looks of all time, because you know Cher's on the list. Post continues below video.
"He started pushing me down the alleyway, and he said: 'If you make a sound, I'll kill you.
"Two fans, who later became friends, saw something was wrong, and they started screaming and ran towards me, and he ran away."
Cher said she is far more hesitant to go out in public these days.
"I don't like going out now because everybody's got a camera and it's not safe. People rush you, and you don't know if they’re going to kill you or take your picture. Either way, I don't like it."
Every aspect of Cher's life has been played out in public - at least for the last 55 years.
