On Sunday's episode of KUWTK, Robert Kardashian (the Second) may have let slip the name of his baby with Blac Chyna, before she even got pregnant. Kris Jenner and Kourtney "The Boring One" Kardashian were having lunch when Jenner got a call from her son Rob. They joked around during the conversation, with Rob joking about a son that he presumably did not and still does not have. Jenner joked back, "What's your son's name, Rob? I forgot" and he answered, "Robert. His name is Robert the Third, actually."
