Of the night in question, she recalled: "I followed them upstairs. I thought, 'What could be going on up here?' Seven girls, one at a time with Hef.
"I was stood at the end of the bed watching them and then I realised they were watching me. I thought, 'This is not a movie. I need to leave.'"
Pamela also spoke about her encounters with Sylvester Stallone who she claimed attempted to woo her by offering her an apartment and a car. However, she went on to admit that the agreement would have meant being in an open relationship with other ladies in his life, a deal she declined.
The Baywatch babe reasoned that she followed her aunt's mantra that "One man can't do it all", as she explained that she has different men in her life that stimulate different parts of her.
Whilst she may have many men in her life, there is only one that currently has her heart, Marseille footballer Adil Rami - who she now lives with in France.
She gushed: "He is fantastic. I love him, of course. I probably should not be talking about it. I am so bad. I have no filter. So bad. You are so good. It is what it is. I am happy in France."
Pamela was previously been married to rocker Tommy Lee, singer Kid Rock and poker player Rick Salomon (who she wed twice).
The blonde bombshell is mother to sons Brandon, 21, and Dylan, 20.
