Why Kourtney Kardashian Has Turned on Rob and Chyna

Kourtney Kardashian appeared to be the only one who stood by brother Rob after discovering he was expecting his first child with Kylie's nemesis. But in an upcoming episode of KUWTK Kourtney does a complete U-turn after she finds out about Chyna's emoji of Kylie Jenner being slapped across the face.

Kourtney was furious saying "that sent me over the edge. Everything with Rob I always try to be super calm but I was just like, in a mood. So I was going to call Chyna, and then Kylie was like, 'No, just call Rob, it's too crazy to call Chyna.' And I don't want to yell at a pregnant person."
