On Monday, Rob tweeted out Jenner's phone number in retaliation for his sisters not inviting his pregnant fiancée Blac Chyna to a baby shower being planned for him. Since then, reports have surfaced that Rob and Chyna are actually broken up and that's why she wasn't invited to the event, but neither has confirmed this rumor.Kardashin told the Watch What Happens Live! host, "I watched a little bit of it but I was on the phone at the same time, a little family drama. Group texting." She didn't elaborate further, so we'll have to use our imaginations to conjure up that text chain.
