Kylie and Rob are TOTALLY having it out on social media right now

As we quite unbelievably learned today, Rob Kardashian is allegedly seeing model Blac Chyna and the Kardashian sisters are not impressed.

In case you didn't know, Blac Chyna is the ex-girlfriend of Kylie's current bae Tyga and according to reports, the 18-year-old is fuming at rumours that her own brother is dating her. 

And if their social media posts are to be believed, Kylie and Rob are not afraid to air their dirty laundry out in the public domain. 

Just a few hours ago, Rob posted a joke meme about Blac Chyna (aka Kardashian-enemy-number-one) having his baby and carrying on the Kardashian name. 

But not to be left out, Kylie Jenner delivered a diss of her own – a swift tweet-and-delete featuring a picture of a devil. 

The best part? She tagged Rob, leaving no doubt as to who her anger was directed at. 

Yep, while the Kardashian clan seem to be in turmoil, they are certainly keeping us all on our toes.
