Pamela Anderson claims Tim Allen flashed his penis at her when she was 23

Pamela Anderson has claimed Tim Allen flashed his penis at her when she was just 23 years old.

Variety has obtained an exclusive excerpt from the actor and model's upcoming memoir, which details the alleged moment between the two.

She wrote in Love, Pamela: "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."

Pamela said she 'laughed uncomfortably' following the alleged interaction.

Variety reports Allen was 'presumably' referring to when Anderson appeared on the cover of Playboy magazine in 1989 when she was 22 years old.

Pamela Anderson had a recurring role on Home Improvement as Lisa the Tool Girl, which lasted for 23 episodes between 1991 to 1993.

The year after she debuted on the long-running sitcom, she landed her iconic role as CJ Parker on Baywatch.

Allen has refuted Pamela's allegation.

"No, it never happened," he said in a statement to Variety. "I would never do such a thing."

In the lead-up to Love, Pamela dropping on January 31, the now-55-year-old has also spoken out against the Pam & Tommy series that was done about her infamous sex tape leak.

The Hulu show focused on her high-profile relationship with Tommy Lee and their subsequent marriage in the 1990s.

During this time, a sex-tape of theirs was stolen and shared without their consent.

Anderson told The New York Times that she hadn’t watched the series, said the events covered were ‘already hurtful enough the first time’, and that she wasn’t in any rush to watch the show.

She added: "It's like one of those things where you're going, 'Really?' People are still capitalising off that thing?"

Lily James was cast as Pamela, who said she tried getting in touch with the former Baywatch star but never heard back.

The New York Times noted that ‘Anderson snubbed her, and a scanned copy of that letter still sits in Ms. Anderson’s inbox somewhere, unread’.

Anderson explained to The Guardian: "It’s not her fault; it’s a job. But whoever created it – well, it just feels like something else stolen."

LADbible has contacted Hulu for comment.

In addition to the Love, Pamela memoir coming out, the 55-year-old will also have a Netflix documentary about her life released on the same day.

It will give viewers exclusive access into her private life and has 'been in the making for several years'.
