TORONTO — Canadian actress and activist Pamela Anderson has revealed she was molested as a child for four years by a babysitter, raped when she was 12 years old and gang-raped only a few years later.

Anderson, 46, stunned guests at the launch of The Pamela Anderson Foundation in Cannes on Friday with the recollections.

“I did not have an easy childhood. Despite loving parents, I was molested from age six to 10 by a female babysitter,” said the former Baywatch star, who was born and raised in B.C.

Anderson also revealed: “I went to a friend’s boyfriend’s house and his older brother decided to teach me backgammon which led into a back massage, which led into rape. My first heterosexual experience.”

Her first boyfriend, in Grade 9, she said, “decided it would be funny to gang-rape me with six friends.”

Anderson said she “wanted off this earth” following the experience.

“I had a hard time trusting humans,” she said. “My parents tried to keep me safe but to me the world was not a safe place.”

Anderson said her father Barry was an alcoholic and her mother Carol worked two jobs. “My mom was always crying, dad didn’t always come home, leaving us in tremendous pain and worry.

She said her parents never knew about the sexual abuse she endured.

“I couldn’t bear to give [my mom] any more disruptive information,” recalled Anderson. “I couldn’t break her heart any more than it was breaking.”

Anderson posted her full speech on her website.

The former Playboy model, whose sex tape with ex-husband Tommy Lee went public, recently re-married Rick Salomon — they were briefly wed in 2007 — after marriages to Lee and Kid Rock.

Anderson has two teen sons with Lee.
