In her new memoirs, Pamela Anderson alleges that Tim Allen exposed himself to her when she was 23 years old.

Pamela Anderson, best known for her role as C.J. Parker on the hit show Baywatch, where the lifeguard team fought crime, saved lives, and had over-the-top adventures, is now 55 years old.

Prior to her role on Baywatch that made her a global star, Anderson had a modeling career with Playboy and one of her first acting credits was on the show Home Improvement, where she played the character of Lisa the Tool Girl.

Tim Allen, who is now 69, also starred in Home Improvement, which became highly popular in the US. This is where Anderson claims the alleged incident of exposure occurred. Allen has denied the allegations strongly.

Anderson has alleged in her new memoirs, obtained by Variety, that Allen exposed his penis to her when they first met when she was 23 and he was 37.

In an excerpt from her book Love, Pamela, she claimed: "On the first day of filming [Home Improvement], I walked out of my dressing room, and Tim was in the hallway in his robe. He opened his robe and flashed me quickly - completely naked underneath.

"He said it was only fair, because he had seen me naked. Now we're even. I laughed uncomfortably."

Anderson had a recurring role in Home Improvement, with 23 episodes between 1991 and 1993, before shifting her focus solely to Baywatch.

Allen has denied the claims made in Anderson's book, with a statement to Variety: "No, it never happened. I would never do such a thing."

Recently, the 69-year-old Allen starred in The Santa Clauses, a TV mini-series that is a continuation of the trilogy films, where his character takes on the role of Santa Claus.

In her book, the Baywatch actress also addressed her relationship with Motley Crue drummer Tommy Lee and shared her thoughts on the popular Hulu series Pam & Tommy, which aired in the previous year.

As the series was about to be released, fans were amazed at how actress Lily James transformed her appearance to look like Anderson, making her almost unrecognizable.

As per TMZ, Anderson's upcoming book is also going to discuss how the 55-year-old considered Lee to be the love of her life, but the scandal of a former employee stealing their sex tape from their home and leaking it online had a negative impact on their relationship.

"Love, Pamela," is set to be released on January 31st, the same day that a documentary about her life will be released on Netflix.
