Former NCIS star Pauley Perrette revealed she's "terrified" of former co-star Mark Harmon.

Ever since the actress left the show in 2017, there has been speculation surrounding her decision to leave—and now, it seems like fans might finally have gotten their answer. At the time, Perrette claimed she experienced “multiple physical assaults” during her time on NCIS, but never named her abuser.

But, in a series of bombshell tweets, Perrette accused Harmon of "attacking" her, adding that she was "physically assaulted for saying no" to him. She later claims this is why she lost her job on the show after 15 seasons.

"NO I AM NOT COMING BACK! EVER! (Please stop asking?) I am terrified of Harmon and him attacking me. I have nightmares about it," she wrote. "I have a new show that is SAFE AND HAPPY! You'll love it!"

"You think I didn't expect blow back? You got me wrong. THIS happened To my crew member and I fought like hell to keep it from happening again! To protect my crew! And then I was physically assaulted for saying NO!? And I lost my job," Perrette tweeted alongside two photos of a person with stitches around their eye.

The actor has yet to comment on Perrette's tweets, but these are some serious allegations.
