Khloe Kardashian Calls Tristan Thompson for 'Complete Piece of S-' for Cheating on Her

Tristan Thompson's cheating scandal unfolded for all to see on Sunday night's episode of Keeping Up with the Kardashians.

As Khloe Kardashian prepared to welcome the couple's first child, True Thompson daughter, on April 12 in Cleveland, she was still reeling from the revelation that Thompson had cheated on her, just after breaking up days before. Nevertheless, the mom-to-be makes you feel good about your baby girl.

"It's important for me to stick to my birth plan, because this is something that I've waited for my entire life," said Khloe, 34. "I do not want to take away anything from this moment. I've always been a big believer of making decisions. I want Tristan here with me, I want to experience this magical moment. "

"I want this for my daughter, and for him, at the end of the day," she continued. "I'm mature enough to say that. I'm mature enough to put some personal feelings aside. Me and Tristan will deal with him and I at a later time, when this is not affecting our child.

Mom Kris Jenner and sisters Kim and Kourtney Kardashian flew in from Los Angeles, and while there are certainly some times in the room, everyone managed to remain relatively cordial.

"The vibe in the room is calm. I thought there would be more tension, "said Kim, 38." As much as I want to go off, I just do not think it's time. So I'm going to keep it cute. I do not have to have a lot of interaction

When True was born at 4:00 a.m – Kris delivered her, and Thompson cut the umbilical cord – Khloe was overwhelmed with emotion.

"You're experiencing a miracle take place," she reflected afterward. "I'm always dreamed of being a mom, and I think I came to the place where I did not know if it was actually going to happen for me. time, for me to give birth – it's just unreal. "

"I feel so blessed. This is something that I've waited for forever. I can not wait to meet her and just spend the rest of my life with her. The minute I put my daughter – I can not believe I'm still saying the words 'my daughter' – I was so in love with her. She's just perfect. "

"I was so anxious about having everyone in the hospital because it was so important that it was a very healthy, happy, positive experience," she added. "And everyone can do their differences for that moment. I'm really grateful for that. But obviously, there's a big elephant in the room. "

As for the state of her relationship with Thompson, 27?

"My focus is not we're going to be together or not," she said. "My focus is just on my daughter and having these beginning moments with my daughter and seeing him as such a great father to her – that's really what's important to me."

Khloe also touched on how she decided on the truth, revealing that it was Kris' mother MJ that suggests it initially. (Khloe's great-grandfather was named True, too.)

"I knew that I wanted the T.T. initials, because I love that my initials are K.K.," she said. "I was at dinner on my mom's house and MJ was there and I told her that. … We're still going back and forth, and we've been really cut. "

A few days later, Kris and her daughters flew back to Cleveland to have a private, off-camera discussion with Thompson about the situation.

"Tristan said to me that he wants to talk with my sisters and my mom. I have my own personal feelings because this happened to me, but they have their feelings and they are very much entitled to that, "Khloé said. "When there's a drama, people love to be like, 'Well, this is my relationship, I do not need to involve people.' Well, in this family, you do."

"I've always been very respectful that this is not Tristan's career, and having conversations like this is not comfortable for me on camera," she continued. "He could not be more vulnerable than he normally would in private. Me and Tristan will deal with this, because there are some things [that are] deeper than being documented. It takes more time than just an episode. "

One of the new faces, the new mom was struggling with the fact that she also had to deal with the situation in the public eye.

"It's so much harder to deal with when it's so public. Everyone is giving you their opinions and their input and their unsolicited advice, "she said. "Even the nurses and the doctors – all kind of like, looking sideways at the whole situation. That's hard, and it's humiliating. "

"He obviously f-ed up, major, but I'm not sure how I feel about everything right now," she added. "In two weeks I might be like, 'You know what? I do not trust you and this is not for me. 'Or I might say,' This is perfect. Let's keep it going. '"

Back in Los Angeles, Kim filled in Cici Bussey's cousin about how the conversation with Thompson went, admitting that she was not help but question that he was sincerely remorseful.

"I told him, 'I think you're more remorseful because it's affecting your job,'" she said. "I think he's more embarrassed than he looks stupid, because of the public … booing him. And I think it's more than anything, and I told him that. "

"I think the convo was going okay at the beginning and then it got heated. I do not know, it just kind of took a left turn, "she added. "Overall, I think it was definitely necessary, and since it is the father of Khloe's baby, I definitely wanted to take the time to hear what he had to say."

Making things even more complicated Ellen DeGeneres Show. Inevitably, she was asked about Thompson and admitted that her actions were "so f-ed up." When she called her sister afterwards to give up her heads up, Khloe sounded defeated.

"It's f-ed up. And he's a complete piece of s-, "she said. "Honestly, you can feel like you want, but I've got other things to deal with right now."

But Kim's interview did not go well with Thompson, and when Khloe told her that he thought she was an "instigator," Kim was furious.

"I unfollowed him on Instagram. He should be embarrassed, "she smoked to Kourtney, 39." I literally wrote to [Khloé] and said, 'Look, let's change the subject. I love you and I support you, but I'm done with him. Over it, she just should have stood her ground.

But Kourtney was more sympathetic, especially because of Scott Disick.

"She should just do it – it's what makes her feel, I've been there," said Kourtney.

"That's not realistic," Kim said.

"I do not think his intentions are right. I do not think he's going to change, "Kourtney said. "But I'm just saying, if she wants to feel like she's doing her own heart and know that she's doing her best, then I do not think there's anything wrong with that. I think it takes a lot more strength to hang in there and try for your family than to just walk away. "

Eventually, Kim relented.

"I will not make her feel bad about anything, but I just do not care about her," she said. "Whatever makes her happy. I'll stay out of the way. "
