Alanis Morissette has claimed she was a victim of multiple incidents of statutory rape when she was just 15.
The 47-year-old singer took "years in therapy" before she realised the true nature of what had happened to her as a teenager because she always regarded having underage sex as fine as she felt she'd given her consent.
Speaking in new documentary Jagged, the Washington Post newspaper reports she said: "I'm going to need some help because I never talk about this.
"It took me years in therapy to even admit there had been any kind of victimisation on my part.
"I would always say I was consenting, and then I'd be reminded like 'Hey, you were 15, you're not consenting at 15.' Now I'm like, 'Oh yeah, they're all paedophiles. It's all statutory rape."
While the Ironic hitmaker - who has Ever, 10, Onyx, five, and Winter, two, with her husband Mario 'Souleye' Treadaway - didn't name her alleged abusers, she insisted she had issued calls for help but music industry figures ignored her.
She said: "I did tell a few people and it kind of fell on deaf ears. It would usually be a stand-up, walk-out-of-the-room moment."
Alanis hit out at those who would criticise her for only speaking out now, insisting it is often the case that women aren't heard when they do try to explain what they have been through.
She said: "You know a lot of people say 'Why did that woman wait 30 years? And I'm like f*** off. They don't wait 30 years. No one was listening or their livelihood was threatened or their family was threatened.
"The whole, 'Why do women wait' thing? Women don't wait. Our culture doesn't listen."
The You Oughta Know singer - who was 15 when she signed her record deal - admitted unwanted sexual advances were common right from the early days of her career.
Referring to a filmmaking shot which suggests tension, she said: "Almost every single person that I would work with, there would be some turning point where the camera would go Dutch angle…
"[It would] either end the relationship or then there'd be just some big secret that we'd keep forever."
