Rob Kardashian is not happy with his sisters at the moment. He took to Twitter to express his anger with them for throwing a baby shower for him but not inviting the mother of his unborn daughter, Blac Chyna. He even went as far to put baby sister’s Kylie Jenner’s phone number on blast. I’m sure her phone was ringing off the hook all day yesterday until she changed it. Rob isn’t playing around with Kim, Khloe, Kourtney Kendall and Kylie I see. Good for you Rob! Stand your ground.
