The Birdsactress told Inside Edition: "It is the worst thing to be the object of someone's obsession if you are not interested... It became unbearable."
Hedren was a struggling single mom with her young daughter Melanie Griffith when the Psycho filmmaker plucked her from obscurity to star in The Birds in 1963.
He followed up that success with Marnie, once again enlisting Hedren to star.
But Hitchcock's interest in Hedren went beyond that of a leading lady. Hedren documents a violent encounter with the filmmaker in her new autobiography, Tippi, A Memoir, on sale today.
"He suddenly grabbed me and put his hands on me. It was sexual, it was perverse, and it was ugly. The harder I fought him, the more aggressive he became," she wrote.
