Khloé Kardashian is not happy her brother, Rob Kardashian, is dating model Blac Chyna. The 31-year-old reality star, who has been trying to help Rob lose weight and get his life back on track, reportedly flew off the handle after learning of his new romance. 

According to TMZ, Khloé came home early from a work trip last week and found the 28-year-old sock designer and Chyna in her kitchen. Sources told the outlet Khloé's Los Angeles home was littered with garbage and it appeared the mess had been there for a few days. 

Reportedly, Khloé went off asking Chyna, "what the f--- are you doing in my house?" The outlet claims Chyna, 27, and Rob retreated to his room but Khloé made both of them leave. She also told her brother he wasn't welcome at her home anymore. Rob has since moved in with his new girlfriend and was spotted in a car outside her gated Los Angeles home Wednesday.

Chyna and Rob's surprise romance has been causing a lot of tension in the Kardashian-Jenner household. A source told People magazine that Khloé is "livid" and feels Rob is disrespecting the family. 

“The drama continues. Rob still has some of his things at Khloe’s house,” the source said. “He hasn’t arranged to pick it up. Khloe knows that he is living with Blac Chyna. Khloe 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."

Radar Online also reports that Kris Jenner is "losing it" and is not happy about the "internal war" going on with her family. 

Supposedly, one of the reasons the Kardashian-Jenner family doesn't like Chyna is because the model allegedly harassed Kylie Jenner when she first started dating Chyna's ex, Tyga. Chyna is also best friends with Amber Rose, who publicly slammed the family over Tyga and Kylie's romance.
