Pamela Anderson has claimed in her upcoming memoir, "Love, Pamela" that Tim Allen "flashed" her when she was 23, on the sets of the popular '90s sitcom, "Home Improvement."

The 55-year-old actress, who played Lisa in the sitcom, recalled her first day on the sets of the sitcom when the alleged incident took place.

"On the first day of filming, I walked out of my dressing room, and Tim was in the hallway in his robe," Anderson mentioned in the memoir, Variety reported Sunday. "He opened his robe and flashed me quickly — completely naked underneath."

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

The 69-year-old actor has, however, refuted the claim. He told the outlet, "No, it never happened. I would never do such a thing."

Anderson worked on the sitcom from 1991 to 1997, and appeared in a total of 23 episodes. Allen, on the other hand, played Tim Taylor's character -- who was featured in 203 episodes from 1991 to 1999.

"Home Improvement" was one of Anderson's early career credits. Following the success of the show, she went on to appear on "Baywatch," which made her a household name in the United States.

Considering Anderson's recent work, she was featured in a horror movie, "Alone at Night," where she portrayed Sheriff Rogers' character. The flick dropped last week on Jan. 20.

She also reprised her "Baywatch" character, Casey Jean Parker, in 2017's remake of the movie, starring Dwayne Johnson, Zac Efron, Alexandra Daddario and Priyanka Chopra Jonas.

There are no upcoming projects of Anderson aside from her memoir, "Love, Pamela," which is slated to hit the shelves on Jan. 31.

The memoir will also address the Hulu series' "Pam and Tommy," which was based on Anderson's stolen sex tape. Lily James portrayed Anderson's character in the series, while Sebastian Stan portrayed Anderson's then-husband, Tommy Lee.

Allen was last seen in a comedy-drama series, "The Santa Clauses," which was dropped on Nov. 16. He was also a regular on the TV series, "Last Man Standing" from 2011 to 2021.
