The event took place to launch her charity The Pamela Anderson Foundation.
The charity describes itself as ‘campaigning for the vulnerable’ and raises funds for animal rights charities and humanitarian causes.
At the event, Pamela decided to reveal a part of her background that she had previously hidden from her fans and the public.
She said: ‘I did not have an easy childhood. Despite loving parents, I was molested from age six by a female babysitter.’
She later revealed that she had been raped before starting secondary school.
The former Baywatch star said: ‘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.’
‘He was 25 years old and I was 12.’
When Pamela reached her teen years, she started dating a boy who ‘decided it would be funny to gang-rape me with six friends.’
‘I wanted off this earth,’ she added.
The event was attended by 200 guests, one of which was particularly impressed with Pamela’s brave and candid account.
‘No one was expecting a speech like that. Pamela was so brave.’
Pamela attended the event with her husband, Rick Salomon, who she remarried at Christmas time.
Also in attendance was her 17-year-old son Brandon.
