That's slightly awkward, considering there have been reports saying Chyna is definitely having a baby girl.
In the preview clip, Rob is hanging out at the barber shop with Scott Disick (you know, typical bro-bonding stuff), when Scott pops the question:
By the way, are you having a boy or a girl?
Rob replies he doesn't know yet, but he wants his child to be a boy so he can "carry on the name."
Scott, with reason, argues the Kardashian name isn't likely to die down anytime soon.
So Rob amends his reasoning, and says,
I'm definitely hoping for a boy because I want to have the same relationship that I had with my father with my son, so that's what I'm praying for.
Again, this is kind of awkward, since Us Weekly reported over a month ago Chyna would be giving birth to a baby girl.
Keep in mind: Reality TV doesn't air in real time, so it's likely this clip was filmed before the couple got the baby news.
Sorry Rob, looks like you're stuck with a dumb girl! Hopefully she never watches your show when she grows up!
"Rob & Chyna" premieres September 11 at 9 pm on E!.
