Tensions are running high in the Kardashian clan over Rob Kardashian's engagement to Blac Chyna.
Sunday night's episode of "Keeping Up with the Kardashians" showed Kim, Kourtney and Khloe's reaction to the news -- after they were totally blindsided by his surprise proposal.
The entire family -- sans Rob -- were on vacation in Aspen when he popped the question, the girls finding out about it via social media.
To say they weren't thrilled about it would be an understatement.
"Rob is just a f---ing p---y," Khloe Kardashian exclaims as she read an article about the engagement on her phone. "He proposed in front of her whole family? So he's engaged to Blac Chyna and you don't even tell your sisters?!"
"We wake up to all of these pictures of my brother just getting engaged," Kim Kardashian explains in a confessional. "I'm just like, is this real, what's going on, how do we tell our mom? Everyone's calling us, asking if it's true and we just don't know. It makes no sense and it's so hurtful."
Khloe goes on to explain that she's just frustrated that he didn't let her in on the news beforehand, especially considering she was so open with him about her relationship with ex Lamar Odom.
"The f---ed up part is we were talking to him all at dinner last night. That's so f--ked up that he did that. My feelings are hurt that he doesn't feel like he can talk to me about that," she tells her sisters. "He was so involved in me and Lamar. I find it weird, he acts like it's two different lives. He doesn't even give me a chance."
Kourtney Kardashian is the only one who appears to be on her brother's side, calling out Kim after she says Rob is "a lunatic."
"That's nice and that's exactly why he didn't tell you," Kourt tells her sis, "because you're a f---ing bitch."
"My brother is the happiest I've seen him in a long time," Kourtney explains in a confessional. "I hope everything is genuine and sincere and that's all we can hope. It's not up to us, why cause any tension and add any drama? We should be happy for him."
The episode ends with Khloe suggesting that someone else might be pulling strings behind the scene, casting doubt on Chyna's intentions with her brother.
"Finding out on social media leaves a really bad taste in my mouth. Now that Rob has figured out where his happy is, instead of sharing that with his family, he's pushing us more away and he keeps doing things to keep this divide between us," she says. "Is someone in his ear telling him this information saying he should handle it? I can't handle it, that's f---ed up."
We'll see the fallout continue next week, as Kris Jenner reacts to the news -- and Kim is heard saying, "he must legitimately hate our whole family."
Kim recently opened up about the family's feelings about the engagement and pregnancy in an interview with GQ, where it sounds like some of their attitudes have changed.
"We're all on board," Kim tells the mag. "We definitely see that my brother is happy and getting healthy, and whatever gets him to that place, you know, we're happy for him. Chyna's a sweet girl, and I think we all have so many things going on in our lives that we just want my brother to be happy. Has there been so many crazy things that happened? Yes. Is the whole situation, you know, just…? I think people want to feel like we're all beefing and have this crazy fight, and we're really not. I think the drama naturally follows us."
