Pamela Anderson has revealed in her upcoming memoir, “Love, Pamela” that she once caught Jack Nicholson having a threesome at the Playboy Mansion.

The “Baywatch” star claimed that Mr.

Nicholson was accompanied by two beautiful women, and they were all giggling and kissing each other.

Anderson stated that she tried not to look but she “couldn’t help” herself.

She recalls bending over the sink to fix her lip gloss, trying to avoid looking at the trio, but she caught Nicholson’s eye in the reflection.

Anderson said that she found herself being slightly involved in the threesome, and that it was just complete freedom.

“It was full of artists, philanthropists, intellectuals, chivalry, beautiful women. It was really an experience,” she told Variety.

She did not reveal when the alleged event occurred.

Reps for Nicholson did not immediately respond to requests for comment on Anderson’s claims.

Nicholson is an 85-year-old actor who has been nominated for 12 Academy Awards and won three.

Anderson has been a cover girl for Playboy more times than any other model and her career with the raunchy mag spanned 22 years.

She first appeared as the cover girl for the October 1989 issue.

Her memoir also dives into her toxic relationship with ex-husband Tommy Lee.

The couple share two sons, Brandon, 26, and Dylan, 25.

Anderson also revealed that Lee had served six months in jail for kicking her as she held their then-7-week-old son Dylan.

While this was the only time Lee was physically abusive towards Anderson, she filed for divorce from him in 1998.

Their relationship was filled with ups and downs, most notably when their s** tape was leaked.

The scandal inspired the 2022 Hulu miniseries “Pam & Tommy,” which Anderson did not support.

“I’m not a victim, and I’m not the damsel in distress,” Anderson writes.

“I’ve made my choices in my life.

“Some obviously were made for me, but I’ve always been able to find myself again.

“And it’s created a strong person and a strong parent.”

Anderson has an upcoming Netflix documentary, “Pamela, A Love Story,” which is set to be released soon.

Anderson was married four other times and is now single.

She has been an actress, model, and television personality, best known for her role as C.J.

Parker on Baywatch.
