Ananova:

Pamela Anderson has revealed she once walked in on an orgy at the Playboy mansion.

The former Baywatch star, who was previously married to Motley Crue drummer Tommy Lee, says stumbled across the sex scene while wandering around magazine boss Hugh Hefner's Los Angeles pad.

She said: "I was over at the mansion and decided to walk around the house.

"So I went upstairs and there's Hef on the bed. There's baby oil, there's toys flying every which way and there's all these girls naked."

But the star, famed for making her own raunchy home video with her former husband, claimed she didn't join in the action, but waited at the door and watched reports Femalefirst.co.uk.

She added: "I was standing in the doorway just looking - for a really long time. It was like watching a movie."
