Kylie Jenner ‘Livid’ About Rob Kardashian & Blac Chyna: ‘KUWTK’ Stars Mocked By Vengeful Rob With Baby Pic?

Kylie Jenner is topping the list of Keeping Up With The Kardashians stars who are upset by Rob Kardashian and his new romance with Blac Chyna. Has Rob taken revenge by hooking up with a romance intended to make his family feel betrayed? Find out just what the Kardashians feel about Rob and Blac Chyna’s new relationship.

Kylie is outraged that her step-brother has hooked up with Blac Chyna, a source told People.

“Kylie is livid,” revealed the source. “She feels super betrayed and can’t understand why someone in her own family would stab her in the back like that.”

Blac Chyna is the ex-fiancée of Tyga, and the couple have a 3-year-old son named King Cairo.

But Kylie isn’t the only one who feels betrayed by Rob. Blac Chyna used to be pals with Kim Kardashian, and that relationship has ended. Moreover, Khloe Kardashian has battled with Amber Rose, who is Blac Chyna’s BFF, about Kylie and Tyga.

Adding to the fuel inflaming those angered by Rob and Blac Chyna’s romance, Tyga was irate with her because she reportedly was claiming that he was unable to pay for the Ferrari he gifted to Kylie when she turned 18. The Kardashians view Tyga as one of the family, even going on vacation with them in St. Barts last summer. He’s also pals with Khloe’s beau, James Harden, and Kourtney Kardashian’s baby daddy, Scott Disick.

But Blac Chyna and Rob are making it clear that they don’t care how the Kardashian family reacts, with Instagram pics that include one from Blac Chyna held by Rob. And it doesn’t stop there.

Blac Chyna & Rob Kardashian Having A Baby?

The picture showed Blac Chyna with a baby carriage and used the hashtag #BabyKardashian.

“Blac Chyna probably out shopping rite now as she plan to give birth to the only next generation of the Kardashian name,” posted Rob for the caption.

Adding to the Kardashian clan clash, a Twitter fan page “UpdateJenner” displayed a drawing depicting a demon. It supposedly was a screenshot of a post by Jenner.

“This is @robkardashian lol,” read the caption.

That photo was reportedly deleted.

But the rift between Rob and Chyna on one side and the Kardashian and Jenner clan on the other exists not just because of Kylie and Tyga. As noted, Amber Rose and Khloe have engaged in a Twitter war, with Kardashian defending her little sister. Chyna’s BFF Amber referred to Kylie as a “baby,” infuriating her protective big sister Khloe.
