Cybill Shepherd claims CBS executives suddenly became more critical of her hit sitcom, and ultimately canceled the show, after she refused Les Moonves’s advances.

“My show could’ve run another five years, but I didn’t fall on the right side of Les Moonves,” Shepherd, who starred in CBS’s “Cybill” from 1995 to 1998, said about the former CBS chairman and CEO in a Thursday interview on SiriusXM’s “The Michelle Collins Show.”

“I wasn’t going to fall at all for Les,” Shepherd, 68, said. She went on to describe a “dinner date” that her assistant and a Moonves staffer set up while her show was still on the air.

“He was telling me his wife didn't turn him on, some mistress didn't turn him on. And I'm watching him drink alcohol and ... he says, ‘Well, you know, why don't you let me take you home?’ ” Shepherd recounted.

“I said, ‘No, I've got a ride.’ And I had my car outside with a good friend of mine who is an off-duty LAPD officer.”

Moonves has been married to Julie Chen since 2004. He was previously married to Nancy Wiesenfeld.

Following the encounter, Shepherd said “shortly afterwards” she would receive critical “notes” from execs about her show.

“Don't have Cybill talk while she's eating,” Shepherd said one note instructed.

“Then it was, okay, we had done one menopause episode, then we were going to do a second one. They said you can't use ‘menses,’ ‘menstruation’ or ‘period,’ and I fought to say ‘period’ and that ended up in Newsweek or Time just that year. I had had to fight to say ‘period,’ ” Shepherd said.

Host Collins then asked Shepherd, “Do you think back to that day and wonder if things had had gone differently, what would have happened to the show?”

“It would have run another five years,” Shepherd replied.

Moonves has been accused by multiple women of sexual misconduct. The longtime head of CBS denied accusations of nonconsensual sexual relationships from several women detailed in a New Yorker report earlier this year, calling the allegations “appalling” and “untrue.”

"What is true is that I had consensual relations with three of the women some 25 years ago before I came to CBS. And I have never used my position to hinder the advancement or careers of women,” Moonves said at the time.

Moonves resigned from his role as CEO at CBS in September.
