“NCIS’ ”Pauley Perrette says she'd never return to acting after allegations against costar Mark Harmon
A year later, apparently fed up with getting the same question, Perrette tweeted in all caps, "No I am not coming back! Ever! Please stop asking?" In the same tweet, she identified her NCIS costar Mark Harmon as a source of her departure from the show, writing that "I am terrified of Harmon and him attacking me. I have nightmares about it."
