So it’s little surprise she’s less than happy about Blac and her brother now being linked with one another.  Kylie Jenner is livid over Blac Chyna and Rob Kardashian’s new relationship, according to US reports. The model and 28-year-old reality star whipped the internet into a frenzy with their very cosy-looking snap which shows Rob’s tattooed arm around Blac’s neck.“The beginning,” she wrote.The 18-year-old reality star and Tyga’s ex Blac have made no secret of the fact they’ve not been on friendly terms ever since Kylie started the Rack City rapper back in late 2014.“Kylie is livid. She feels super betrayed and can’t understand why someone in her own family would stab her in the back like that,” a source told People magazine.
