'A little disrespectful': Kylie Jenner seethes at Rob Kardashian after house trashed following scrap with Blac Chyna on latest episode of KUWTK

• e-mail

Kylie Jenner was furious with Rob Kardashian and on-off girlfriend Blac Chyna on Sunday's episode of Keeping Up With The Kardashians after they trashed her house.

The family tried to force Rob, 30, into an intervention to leave his lover because they were so worried about their 'toxic' relationship.

Their fears reached a peak when police were called to the house because of disturbing social media posts Rob made after Chyna fled the house with their newborn daughter Dream.

House trashed: Kylie Jenner got fed up with brother Robert Kardashian after her house was trashed on Sunday's episode of Keeping Up With The Kardashians

His mother's boyfriend Corey Gamble admitted people feared he was suicidal.

Kylie, 19, was especially upset because she had let the couple live in one of her homes — even though Chyna was famously an ex with her own then-boyfriend, rapper Tyga, having her first child, King Cairo, with him.

The teenage cosmetics mogul revealed in an on-camera confessional that Rob had only asked her 'if he and Chyna could move into one of my old homes' about a week before the fight.

'I agreed, cause me and Chyna kinda put everything behind us, and my brother seemed really happy and I wanted him to enjoy his new life and I wasn't here to block anyone's blessing,' she said.

Huge misunderstanding: Rob insisted to his family that he and Blac Chyna were doing fine

Really unhealthy: Kylie characterized Rob and Chyna's relationship as 'really unhealthy'

'But my mom calls me to kind of keep me informed on what's going on in my home, and apparently Chyna threw something at my television that I left there. It's just a little disrespectful and I wouldn't do that in anyone else's home,' Kylie said.

Kylie said she felt Chyna 'just doesn't like' her brother, and added: 'It's really hard to support a relationship that's really unhealthy, especially when it's hurting my brother and now it's affected me.

'I just wish they could just stop this kind of roller-coaster ride.'

House update: Kris Jenner called Kylie to give her an update on her home

Corey, who was first to rush over during the fight, called her with his own update, saying: 'If I wouldn't have got there it would've been really bad.'

He added of new mom Chyna: 'Her hands were f***ed up. One of her real whole nails was gone. She was trying to bust his car window.'

'It's just really sad and I don't think it's going to end well,' Kylie told sister Kendall of their brother's fiery relationship.

Cause for concern: Kendall Jenner looked on as Kylie got the call about her house

Throughout the episode, Rob's siblings were united in attacking the relationship — with them seeming more upset when Rob traveled to New York with his on-off girlfriend as if nothing had even happened.

'Why does he switch his mind — like, what is wrong with him?' Kourtney asked her family. 'I feel bad for his mental state.'

'I really thought there would be no way in hell that he would forgive her, but also that she would want him back,' Khloe said, also asking: 'The things she was saying and doing and the names she was calling him — why do you want him back if you think those things of your significant other?'

Group call: Khloe, Kim, Kourtney and Kylie talked to Rob over the phone about him and Chyna

Khloe also called the relationship 'dark and toxic' and at one point reminded him: 'Rob, she texted all your sisters and said she's disgusted by you and that she's ready to leave you because you can't get your s*** together.'

Kim also said the relationship 'just isn't that healthy,' adding: 'It's so clear what this relationship is and that they're just not meant to be with each other.'

Even mom Kris told them with obvious confusion: 'You know what Rob does all day long? Call her names, and says she's a lot worse things.'

Dark and toxic: Khloe reminded Rob that Chyna sent his sisters nasty texts about him

Travel together: Rob and Chyna traveled to New York City together for an event

His sisters and mother even met for a family dinner to discuss how they could help Rob end the relationship — especially amid his attempts to push for a second series of his own spin-off reality TV show, Rob & Chyna.

'Rob, you have your head so far up Chyna's a**,' Khloe angrily told her brother when they FaceTimed him from the restaurant, with him getting angry and hanging up after saying: 'Yo I'm done, I'm done.'

But the conversation continued, with Kendall Jenner clearly angry that they would even consider letting them continue with their TV show, asking her mom angrily: 'So why would you want to put them in a show together? That's the craziest thing I've heard, that everyone's lives revolve around a show — you make someone happy with a show?

Craziest thing: Kendall got angry over the suggestion that Rob could be made happy with a reality show

'That's the most sad, depressing thing.'

Kim and Kourtney both replied in unison that it was 'a job' while Kris insisted that 'the show is what got him out of bed. He's not in a dark room.'

'Get your head together! Get your s*** together! Move out. I am completely 150 percent a thousand right,' Kendall said of what her brother needed to do rather than fight for a relationship and put it back in the spotlight.

Hold on: Kris reminded Kendall that the reality show got Rob 'out of bed'

Her sisters agreed that their brother may have misdirected motives for the show, with Kourtney saying: 'I would say the show has made Rob care way more about what other people think about him — which is not healthy.'

'I think my brother is trying to hold onto his show because it's his way of holding onto Chyna, his way to make Chyna happy, and it's trying to please someone else,' Kim admitted later to camera. 'I think it's just too much.'

She also claimed: 'I get it that Rob thinks the show is helping him find himself, but I think that if there's no show there's no relationship.'

Too much: Kim believed that Rob wanted the reality show to maintain his connection with Chyna

Khloe, meanwhile, insisted: 'This is such a toxic relationship and we all don't think it's a good idea that they film this show.

'I don't want my brother to keep getting taken advantage of. Does she keep communicating with you if you aren't filming? To me it doesn't look that way,' Khloe said.

Rob later emailed his sisters to assure them he was 'looking to be the man that you all are proud of' and insisting: 'I love Chyna and want to be able to tell my daughter that I did everything that I could to make it work with her mother.'

Love declaration: Rob emailed his sisters and declared his love for Chyna

United front: Kim and Kourtney after reading the email summoned Rob for a family intervention

Instead of replying, they summoned him for a family intervention, though with only Kim and Kourtney eventually showing because Khloe was supporting their mother over her own heartache over ex Caitlyn Jenner's book and claims about their relationship in it.

He seemed more open to their fears, and told them of his relationship: 'Right now we're good. One day we're fighting, one day we're not. I don't mind that when everything's good.'

He insisted: 'It's never been anything that's made me want to give up on her — we've just had a baby, so… I envision being with the person I had the baby with.

All good: Rob told Kim and Kourtney that he and Chyna were doing fine

'I definitely do love her and want to be with her — I'm not gonna just give up.'

'I really feel that Rob is taking in what we've been telling him and is taking the steps to just better his life,' Kim said after the meeting.

Rob - who also sat down with his mother to try to reassure her that he was trying to do the right thing — said later: 'Obviously I love all my family, my mom and my sisters, but how they feel about Chyna and the negative things — I feel like nobody's on the same page and I feel they just take things the wrong way or feel that I'm unhappy.

Different pages: Rob felt that he and his family were on different pages regarding Chyna

'I feel like it's just a huge misunderstanding.'

'I love my kids more than life itself,' Kris said later to camera. 'I want them to be happy and I want them to make good choices. But I can't be in the middle all the time.'

Kris had her own anger and heartache after trying to patch up her relationship with Caitlyn Jenner, taking her up on an offer for them to have a gold facemask treatment together and later inviting her over for a chat over wine.

Meeting up: Kris and Caitlyn met up and discussed their different lifestyles

Even at the idea of meeting up again, Kris admitted her 'emotions are definitely a roller-coaster when it comes to Cait,' but she said: 'I definitely feel that it's healthier as a family to have a relationship with Cait so for the sake of my kids I'm really trying to be a good friend.'

They then joked about how Caitlyn — then living as her husband Bruce — would steal all her makeup, letting their daughters take the blame, and even how Kris always wondered why Bruce had used the toilet sitting down.

Caitlyn invited Kris to come to her house when she needed peace, with Kris returning the offer for Caitlyn to come to her home whenever she wanted 'action' with all the noise and activity.

'Those were the old days when I came here for action,' Caitlyn quipped.

But the civility ended after Caitlyn left a copy of her upcoming memoir The Secrets Of My Life, with Kris close to tears as she told Kim and Khloe about what she read.

Saying that the only nice thing Caitlyn, 67, said about her was that she was great socially at a party once, she fumed: 'None of it makes sense. Everything she says is all made up. Why does everything have to be that Kris is such a b**** and an a**hole?

Advanced copy: Kris was not pleased with her depiction in Cait's memoir after reading an advanced copy

'All through the book, Kris knew. ''Kris knew before I even made love to her.'' I'm like, 'What!?'

'I've done nothing but open up my home and my heart to a person who doesn't give a s***. So I'm done.

'I've never been so angry and disappointed in somebody in my whole life. I'm done - done. Doneso. Sorry.'

Book review: Khloe listened as Kris said she was done with Caitlyn

Kris added later to camera: 'I'm not gonna be used as a person who benefits someone else's life just to make them look better. I just can't sit back and be an enabler anymore.'

Kim added separately: 'My mom's been putting in so much effort, trying so hard to have a good relationship, for their kids together. Caitlyn has every right to feel however she feels but why bring my mom into it one more time. I just feel so bad for my mom.'

Kim, meanwhile, teased younger sister Kylie about reports she was taking her 'throne' as the queen of social media, telling her mother at dinner as Kylie sat next to her: 'If it isn't bad enough that Kylie is coming for my throne and we have major beef — this f***ing ho over here, that ho over there decides to try to copy me again — she got f***ing psoriasis. She has psoriasis,' she said, having told her 'welcome to the club' when she saw the skin condition on her abs earlier.

Not enabling: Kris said that she refused to be used by Caitlyn and and would not be 'an enabler anymore'

Kylie took the ribbing in good humor, explaining later: 'Everyone thinks that I'm coming for Kim's throne but we actually have a really a funny, good relationship and we talk all day long, so it's kind of funny that people think that and we like to play along.'

But Kim definitely stunned Khloe when she showed her her 'ex-box' of bizarre memorabilia she had saved from her time with first love, Michael Jackson's nephew, Tito Joe Jackson, or TJ.

Khloe was shocked when Kim pulled out her prom photos, petals he gave her on their 'one-month anniversary,' a balloon, and various memorabilia from Neverland, including a map, chocolate and even the confidentiality agreement she had to sign.

'That to me is just like hoarding,' Khloe told her.

'You mean you don't keep the chicken nugget box from your first date?' Kim said, pulling out that exact item as Khloe looked on with eyes wide-open with shock.

'A 9-peiece chicken MgNugget with some grease in there… you don't want to keep this?' Kim asked with a smile.

'I think probably 70 percent of it is probably burn-worthy,' Khloe said, having admitted she was even considering destroying her photos from her wedding to Lamar Odom.

Kim told her sister that she had only told husband Kanye West about the ex-box that morning, saying: 'He could care less.'

Khloe — who said she would just look on the Internet if she wanted to see a photo of an ex — celebrated changing her name back to Kardashian from Odom with a cake of her new driving license.

'My divorce has been, like, the longest divorce in history, I swear. But it's final, yay!' she said.

'I finally get to change my last name back to Kardashian, and just to move on with my life.' 

Keeping Up With The Kardashians will return next week on the E! channel.
