Pamela Anderson has claimed she once walked in on Hollywood actor Jack Nicholson having a threesome at the Playboy mansion.
The Baywatch legend, 55, said she caught 85-year-old Jack with "two beautiful women" when she went into a bathroom to fix her lip gloss.
Pamela is currently awaiting the release of her bombshell memoir and has recently made a series of shocking claims about a number of celebrities.
