We're told it all went down last week, when Khloe returned home early from a trip promoting her new show. She walked into the kitchen and found Rob and Chyna standing there. There were liquor bottles and trash strewn about, and it appeared the 2 had been there for days.
Our sources say Khloe became enraged and asked Chyna, "What the f*** are you doing in my house?" The 2 bolted into Rob's wing and locked the door ... Khloe followed suit and told them both to "get the hell out." Khloe made it clear to Rob, he was no longer welcome in her home.
We're told Khloe's view was that she was exercising tough love on Rob, because she felt he was falling off the wagon and Chyna was preying on him.
Our sources say Rob's family was especially indignant when she learned Rob had purchased some expensive items for Chyna, and he doesn't have a lot of money to burn.
And we're told, there's a reasonthere's bad blood between Chyna and the Kardashian women. We're told when Tygafirst hooked up with Kylie, Chyna followed Kylie around and harassed her. The sources say she also sent her threatening messages.
Rob Kardashian packed a suitcase and moved in with Blac Chyna ... at least temporarily ... TMZ has learned. Rob, who was living at Khloe's house, has been at B.C.'s digs for 5 days and counting. As for how it happened ... we're told Rob made the first move by DM'ing Chyna 2 weeks ago.
We're told Rob genuinely likes Chyna and is not hooking up to upset his family ... but we're told it has definitely upset the Kardashian brood. Kylie has been at war with Tyga's baby mama for more than a year.
Rob is using Chyna's home fitness equipment to train, with a little inspirational help from her.
Rob and Chyna have known each other for a long time ... since she lived across the street from him when she was Kim's best friend.
Our sources say the Kardashians are outraged at Rob's hookup. They believe Chyna is manipulating everything and that SHE is the one who first reached out. They also say she's behind Rob's sudden interest in Instagram postings. They believe Rob's horribly depressed and she's playing into his insecurities for her own gain.
