Rob's post comes only a few days after the 27-year-old model seemed to be calling out his sister Kylie Jenner, who is dating Chyna's ex Tyga, for copying her cooking show idea. "Bi**h Bye," Chyna wrote on Instagram. "Follow @cookingwithchyna #InfatuatedWitChy."
Tyga, who has a son with Chyna, defended Kylie in a NSFW Snapchat video on Monday night. "In 2016, mother f**kers need to stop acting like they invented every mother f**king thing out here," the 26-year-old rapper said to camera.
It's still bizarre timing for Rob to post a message about disowning his family. On Tuesday, ET confirmed that Kris Jenner had purchased a $2.3 million, 4,256 sq. ft home for her only son. The house was bought under the family trust and is located in an upscale gated community in Calabasas, California.
The location of the new home is conveniently close to Rob's famous family. His sisters, Khloe and Kourtney Kardashian, and Kylie, all live in the same gated community, while Kris and sister Kim Kardashian West live about a mile away in Hidden Hills, California. Chyna lives in Tarzana, which is less than a half hour drive from Calabasas.
When ET spoke with Kris earlier this month, she admitted that she's out of the loop about her son's new girlfriend. "I don't really know much about their relationship. I think they're definitely friends, and they seem great," the 60-year-old momager said. "Rob has been in a really good place for a while. He's on it right now, and he's engaged [in life]. I love seeing him happy about what he's doing."
