Actress Pauley Perrette says you won’t ever see her on the hit CBS show “NCIS” again — because she is “terrified” of star Mark Harmon.

In heated tweets early Friday morning, the actress appealed to her fans to stop asking when she would return to the series, saying she still has “nightmares” of Harmon attacking her.

This wasn’t the first time Perrette, who played forensic specialist Abby Sciuto, claimed she was physically assaulted on set. In May 2018, as she was exiting “NCIS” after 15 years, she tweeted that she had suffered “multiple” attacks and that she felt her crew was in danger.

Though she didn’t specifically reference “NCIS” or Harmon, she did hint that a man was involved: “No morals, no obligation to truth, and I’m just left here, reading the lies, trying to protect my crew. Trying to remain calm. He did it.”

In a second bombshell tweet Friday, Perrette shared photos of an alleged crew member’s battered eyes. “THIS happened To my crew member and I fought like hell to keep it from happening again!,” the 50-year-old alleged. “And then I was physically assaulted for saying NO!? and I lost my job.”

Harmon plays the leading role of Leroy Jethro Gibbs on the long-running show. Though there were rumors of his departure in late 2018, they had to do with his health, not his behavior. Harmon dispelled the rumors at the time, though he has not yet commented on Perrette’s latest claims.

This isn’t the actress with Bettie Page bangs’ first high-profile brush with violence. Perrette was reportedly attacked by a homeless man in 2015. In 2018, she expressed great fear of his impending release from a psychiatric hospital.

At the time of Perrette’s original allegations, CBS Television studios was supportive, saying, “Over a year ago, Pauley came to us with a workplace concern. We took the matter seriously and worked with her to find a resolution. We are committed to a safe work environment on all our shows.”

Perrette was pleased with the response at the time, writing, “I want to thank my studio and network CBS. They have always been so good to me and always had my back.”
