Casey Wilson blasts ‘bitch’ Tim Allen for ‘f–king rude’ behavior on ‘The Santa Clauses’ set: ‘Worst experience’

Despite playing Santa Claus, Tim Allen might not be so merry after all.

On a recent episode of “Bitch Sesh,” co-host Casey Wilson claimed the famous actor and comedian acted more like The Grinch when they shot a scene together for “The Santa Clauses” television series, in which he stars as the jolly, white-bearded man.

“Tim Allen was such a bitch. It was the truly single worst experience I’ve ever had with a co-star ever,” she slammed.

She elaborated on her point by recalling a scene in which she was supposed to mistake Santa as an intruder.

“So I’m throwing things at him. [He] goes over to the producer who is standing four feet from me and goes, and I hear him, he goes, ‘You gotta tell her to stop stepping on my lines,’” the “Saturday Night Live” alum claimed.

“The producer turns to me with horror on his face and has to walk one foot to me and he goes, ‘Um, Tim would ask that you stop stepping on his lines.’”

Wilson also claimed “everybody was walking on eggshells” around Allen, 70, and that crew members appeared “frantic.”

“When he was done,” she continued, “he was so f–king rude. Never made eye contact, never said anything. It was so uncomfortable.”

He did, however, allegedly let people know when he was done filming with a curt announcement.

“It’s the end, and Tim Allen goes, ‘Leaving!’ takes his Santa cape, picks it up and drops it on the floor and walks out,” the “Gone Girl” actress, 43, claimed.

“And they hustle in his stand-in; lovely man, who was much nicer to act against. People are scurrying to pick up his velvet Santa coat. He’s a bitch.”

Wilson also alleged that a crew member informed her that she was “seeing him on a good day.”

Page Six did not immediately receive a response from Allen’s representative regarding Wilson’s comments.

The actress guest starred in the show’s debut episode, which dropped in November 2022.

Pamela Anderson claimed in February that Allen flashed her on the set of “Home Improvement” in the 1990s.

Its two seasons are available to stream on Disney+. A third season has yet to be announced as of this writing.

“The Santa Clauses” is a sequel to Allen’s beloved movies, 1994’s “The Santa Clause,” 2002’s “The Santa Clause 2” and 2006’s “The Santa Clause 3: The Escape Clause.”

This isn’t the first time Allen has been under fire for inappropriate conduct on set.

“On the first day of filming, 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,” she wrote in her memoir, “Love, Pamela.”

He denied the accusations, saying he would “never do” such a thing.
