Congrats to Rob Kardashian and Blac Chyna as they have revealed they are having a baby girl!

They announced the news on their new reality show, Rob and Chyna, that debuted on E! Sunday night.

In the clip, the couple heads to the doctor to find out if they are having a boy or a girl.

Kardashian admits, “I’m pretty nervous. I’m excited. I really want a boy,” before the doctor reveals, “You are having….a girl!”

Chyna was ecstatic and said, “Rob, it’s a girl!”

And Kardashian’s response a little bit different.

“Oh, that’s crazy.”

The doctor points out that Chyna is mom two a boy, King Cairo. But Kardashian reminds the physician that King is not his biological child.

“It’s an emotional moment,” Kardashian admits. “Me wanting to have a boy, it definitely stems from my dad but I’m sure I’ll have the same relationship that I had with my father with my daughter. I’m just happy that the baby’s healthy and I’m gonna be super happy with a girl.”

As if right on cue, the doctor adds, “That’s a nice, normal heartbeat. It’s regular and there’s no problems with the beat of the baby’s heart.”

Chyna and Rob announced their new bundle of joy earlier this summer. Kardashian also popped the question to Chyna. They revealed via On Air With Ryan Seacrest whether any of Kardashian’s sisters will be bridesmaids.
