Oh no! On Tuesday, May 8, Pauley Perrette officially said goodbye to NCIS and her beloved character, Abby Sciuto, after appearing on the show for 15 seasons. But now, she's implying that she was physically assaulted on the set of the series in her latest Twitter rant, which may have contributed to her reason for leaving.

There have been a plethora of different rumors going around about why Pauley left the show, so she angrily took to social media to clear things up. "I refused to go low, that's why I've never told publicly what happened. But there are tabloid articles out there that are telling total lies about me. If you believe them? Please leave me alone. You clearly don't know me (Sorry guys, had to be said)," she wrote. "Maybe I'm wrong for not 'spilling the beans.' Telling the story, THE TRUTH. I feel I have to protect my crew, jobs and so many people. But at what cost? I don't know. Just know, I'm trying to do the right thing, but maybe silence isn't the right thing about crime. I'm… Just… ?"

And Pauley didn't stop there. "There is a 'machine' keeping me silent, and feeding FALSE stories about me. A very rich, very powerful publicity 'machine.' 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. I've been supporting anti-bullying programs forever. But now I KNOW because it was ME! If it's school or work, that you're required to go to? It's horrifying. I left. Multiple Physical Assaults. I REALLY get it now. Stay safe. Nothing is worth your safety. Tell someone."

In addition to Pauley's serious allegations, sources are suggesting that she could have possibly been calling out longtime co-star, Mark Harmon. According to reports obtained by Celebrity Insider, Pauley and the lead actor did not get along as a result of an accident that took place in October 2016 involving Mark’s pet pitbull who seriously injured a crew member.

According to insiders, Pauley was “furious at Mark for putting the cast and crew in danger, and from that point forward she started to act like a diva. She refused to shoot scenes with Mark and wouldn’t even sit on the same side of the table during table reads.” However, there's no definitive proof that her lashing out on social media had anything to do with Mark or the incident.

Pauley's confession comes shortly after the actress shared that her decision to leave the police procedural drama was far from easy. "I, like, usually cry in my car every single day when I drive to work," she recently told NBC News. "And I usually cry on my way home at some point. And then I take a deep breath, and I go, 'All right,' you know? It makes me sad to imagine a world without Abby in it. It really makes me sad… Abby made science cool and attainable for young women. And this television character did more than encourage it. It made it cool. It made it exciting. It made it fun."

She also made it seem like she left because it was simply time to move on to other projects. "I believe in God and the universe so firmly, and it just suddenly became blindingly apparent that now was the time. After a lot of thought, I decided to announce it myself on Twitter because I didn't want it to be turned into anything 'shocking.' Abby leaving is more than a cheap TV ploy," she said in a previous interview, according to E! News.

In October 2017, Pauley had announced her plan to leave the long-running series. "So, it is true that I am leaving NCIS after this season. There has been all kinds of false stories as to why (NO I DON'T HAVE A SKIN CARE LINE AND NO MY NETWORK AND SHOW ARE NOT MAD AT ME!)," she wrote on Twitter. "It was a decision made last year. I hope everyone will love and enjoy EVERYTHING ABBY not only for the rest of this season but for everything she has given all of us for 16 years. All the love, all the laughter, all the inspiration… I love her as much as you do."

As for Pauley's character, Abby, she decided to leave the NCIS unit to honor a fallen team member. In the May 1 episode titled "One Step Forward," Abby and MI-6 officer Clayton Reeves (played by Duane Henry) were confronted by a gun-wieding thief and the show ended on a cliffhanger. Then, one week later on the May 8 episode titled "Two Steps Back," Abby appeared hospitalized and in critical condition after being shot in the chest. Clayton sadly died from the injuries he sustained.

After Abby awoke from being in a coma, she told her NCIS co-workers that she planned to leave the team to instead carry on Clayton's philathropic legacy. "Clay died saving my life, and I owe him a debt and I intend to see it through. Clay always wanted to start a charity in honor of his mom and since he's not here to make that happen, I will. I know you may not understand, but it's something I have to do — and not just for him but for me," she said during the emotional episode.

After CBS showrunners learned Pauley was leaving the show, they planned a "special send-off" for the actress and her character. "We've known for some time this would be Pauley's final season on NCIS and have been working toward a special send-off. From day one, she has brought incredible passion and specificity to the role. Abby is a character that inspires millions of fans around the world, and all of us at NCIS are appreciative of Pauley for portraying her," executive producers George Schenck and Frank Cardea said in a statement to E! Online.

Pauley previously made her debut as Abby alongside NCIS characters Leroy Jethro Gibbs (played by Mark Harmon), Anthony DiNozzo (Michael Weatherly), Vivian Blackadder (Robyn Lively), Don Dobbs (Tom Jay Jones), and Tom Morrow (Alan Dale) in the Season 8 JAG episode "Ice Queen." The show acted as a backdoor pilot for NCIS which later premiered on CBS in September 2003.

Just before the Season 8 NCIS premiere in 2010, Pauley gushed about portraying Abby on the successful series. "To be able to play the iconic character of Abby on a show where the entire cast and crew is still excited and in love with the show is a blessing that comes along… Like never. People always say it looks like we are having so much fun, and we are! It’s great. I’m grateful," she told TVEquals.com at the time.

Interestingly, Pauley isn't the first NCIS star to announce their departure in recent years. In January 2016, Michael Weatherly (aka Anthony DiNozzo) revealed he was leaving the program after more than a decade. "After 13 years on NCIS, Michael is leaving the show at the end of this season," the network said in a statement. "He is a valued part of the CBS family, and the immense charm and talent he brings to the screen as 'Very' Special Agent Tony DiNozzo has helped make NCIS what it is today — the No. 1 drama in the world."

So, what's next for Pauley after leaving NCIS? "It is totally God's plan for me, and that's what I believe and that's how I feel,” she explained to Entertainment Tonight. “So I'm just waiting. It'll be revealed to me. I'll know when it happens.” We wish Pauley all the best in her future endeavors!
