TMZ reports that Khloé found Rob and Chyna in her kitchen after she returned early from an NYC promo trip and asked Chyna, "What the f**k are you doing in my house?"
After Khloé allegedly told them to “get the hell out” of her home, she told Rob that he was no longer welcome to live in her home.
Another source told People about the deteriorating relationship between Rob and Khloé, "The drama continues. Rob still has some of his things at Khloé's house. He hasn't arranged to pick it up. Khloé knows that he is living with Blac Chyna. Khloé feels very betrayed. She always stood up for Rob and defended him. She has gone out of her way a million times to help him. She is very frustrated at the lack of respect for his family."
Rob’s new relationship with Blac Chyna seems to be an escape for him since he has struggled with depression and weight gain over the years. The insider added, "Rob has been lonely for so long, so of course it's great for him to spend time with someone other than his sisters. Rob likes her and seems to think it's mutual. It's just hard to take things seriously since obviously both share a lot of anger toward the [Kardashian-Jenner] girls. They have both had a lot of drama with Kim. Rob really seems to get a kick out of all the drama that he is causing."
There is bad blood between Chyna and the Kardashian clan after Chyna reportedly harassed Kylie for dating her ex, Tyga.
