While giving a speech at the Cannes Film Festival in France on Saturday, May 17, Pamela Anderson opened up about her troubling childhood and history of sexual abuse.

"I feel now might be the time to reveal a few of my most painful memories," she said during the launch of her animal rights charity group, The Pamela Anderson Foundation, according to the Huffington Post. "At the risk of over-exposing myself, again, or being inappropriate, again, I thought I might share with you why I am doing this."

The Playboy model went on to reveal that she was first molested at the "age of six by a female babysitter."

She was raped again six years later when she went to her friend's boyfriend's house. "His older brother decided to teach me backgammon, which led into a back massage, which led into rape - my first sexual experience. He was 25 years old and I was 12," she said.

The former "Baywatch" beauty also described a third tragic experience when her ninth grade boyfriend "decided it would be funny to gang-rape me with six friends," said Anderson adding, "I wanted off this Earth."

The 46-year-old model explained that being sexually abused made it extremely difficult for her to trust people. "Needless to say, I had a hard time trusting humans," she said. Instead, "my loyalty was to the animal kingdom, I vowed to protect them and only them. I prayed to the whales with my feet in the ocean. My only real friends, till I had children."

The actress also revealed that she never told her parents about the sexual abuse. Although her parents "tried to keep me safe," the "world was not a safe place," she said, reports CNN.

"My mom was always crying," she said. "I couldn't [bear] to give her any more disruptive information," she said. "I couldn't break her heart any more than it was breaking."
