"I don't know what it looked like from the outside. But I know what was going on inside and it was horror... I remember opening my eyes, Kim Fowley was raping me, and there were people watching me."
Her account has been backed up by The Runaways singer Cherie Currie and teenage songwriter Kari Krome, who were in the motel room when the rape incident took place.
Krome, who was 14 at the time, says it "turned into this really disgusting theatre performance".
"Jackie was dead drunk - like corpse drunk. She was just laying down on her back, sound asleep, out of it. He had to manually move her body parts into positions that he wanted for himself.
"I didn't know what to do. Go outside, drive, find a pay phone and call the police? I didn't want to call the police on anyone - but at the same time I knew what was happening was wrong."
Fox says none of her colleagues wanted to discuss the alleged rape afterwards and so she decided not to talk about it.
She claims the shame and torment she felt led her to attempt suicide during a tour of Japan in 1977. She quit the band shortly afterwards and was replaced by Victory Tischler-Blue.
Fox, now 55, only decided to go public with her rape ordeal after realising her story could help others.
