Kourtney Kardashian's sisters have had enough!
On the latest episode of Keeping Up With the Kardashians, the catfight between the famous beauties continued and even worsened when Khloe and Kim blamed Kourtney's new therapist and new boyfriend for making her "so nasty."
Family BFF James Corden offered to mediate, but instead, the girls brought in a neutral therapist to repair their broken relationship.
"She's such a b***h ," Kim, 37, and Khloe, 34, said about Kourtney, 39.
"I think her therapist is a lunatic. We got into this big fight and she said: 'My therapist told me this would happen.'"
"If you're watching we hate you," Kim and Khloe said to the camera, addressing their sister's therapist.
Running out of ideas, the ladies tried asking Scott Disick for help.
"She's just a raging lunatic," said Khloe.
"Somebody should get to the bottom of it before she kills one of us," agreed Scott.
Soon, the three girls got together inside Khloe's home, but Kourtney refused to even make eye contact with her sisters, instead choosing to stare at her phone the entire time.
"We all have different realities of what goes on when we fight," Kim said. "We just don't ever express what's really bothering us. We are all going to therapy together. We need to communicate with each other."
Kourtney defended herself. "I don't hate you because of my therapist. My therapist said people that you're close to, you'll have arguments with them. I don't think we need to go to therapy, I think we need to talk."
"We always sweep things under the rug and don't talk," Khloe said, but Kourtney ignored her two sisters with a smirk on her face.
"I want to f**king punch that smile off her f**king face," Khloe said during her confessional.
"So weird her little smirk," Kim said after she and Khloe left the room. "If you don't want to fix the problem don't be here," Khloe said.
A tearful Kourtney tried to explain to her sisters why she was upset. "They just don't have my back and they don't take my feelings into my consideration. I don't even want to be around my sisters because it gives me anxiety."
Khloe then explained the problem to momager Kris Jenner.
"There's two new things, her boyfriend and her therapist. Ever since then she's been a raging b*tch. It is so rude. It's not how you raised any of us," Khloe told Kris.
"She's so not engaged and I think that is what infuriates everyone. I think everyone just has a breaking point."
Desperate to end their feud, the girls invited therapist Anita Avedian to mediate.
"I think we need to learn how to communicate better," Kourtney said during the session. "I'm the one who invented mean fighting. I don't want to be like that anymore. I don't want to be mean and I don't want to spend my time around people that are mean and are putting me down."
"You surround yourself with people who are the opposite. Most of the time you're arguing stuff. She's always anxious and insecure," a shocked Kim told the therapist about her sister.
"Recently, ever since with the therapist I feel like she is angry towards me or is annoyed with me," Khloe said. "We have a really special bond. I haven't felt that from her in the last couple of months. I feel a major disconnect."
Kourtney explained her misery, saying that she needed to take week-long trips every six weeks so she could spend time with her new boyfriend, who lived out of the country.
"I think Kourt is going through something but she can't commit to filming a show and a season if she isn't going to share her life," Kim said. "We want Kourtney to take her trips, live her life and do whatever she wants to do. But we just want her to be accountable when you take a job."
Khloe then detailed Kourtney's her poor work habits, adding that they were all frustrated with her.
"Working is not my top priority," Kourtney admitted. "I feel like my sister really aren't hearing what they're saying. I just don't know how this is going to change moving forward. Everyone is selfish in their own situation. I'm evolving. I don't want to be the b***hy not in touch with my feelings person I was in before."
"The reality is that she was really rude and you can't deny that," Kim pointed out.
"Let's be sensitive with each other," the therapist suggested after Kourtney said her sister was not being supportive.
"I want to fix our relationship. I feel like we agree to walk on egg shells. Kourtney wants to live in these fake relationships. This is the fakest one," Khloe slammed.
