Sorry, Rob. Looks like you are doomed to remain the sole male Kardashian.

On Sunday's premier of the latest Kardashian spin off show Rob & Chyna, Rob and his fiancée found out that they are expecting a baby girl. Rob, who was pretty vocal about wanting a boy, had a lukewarm reaction to finding out about his daughter-to-be. Seriously, how much estrogen can one man handle?

In the past, Rob revealed he wanted a son because he was hoping to replicate the special relationship he had with his father, the late attorney Robert Kardashian.
