"It's a girl!" Rob Kardashian and Blac Chyna just announced the gender of their upcoming bundle of joy during the pilot episode of the couple's reality TV show "Rob & Chyna" on Sunday

In the said episode, the couple made a doctor's appointment to determine whether it's a boy or a girl.

"I'm pretty nervous. I'm excited," The soon-to-be-dad revealed. "I really want a boy."

Then the doctor announces, "You are having...a girl!"

"Rob, it's a girl!" Chyna exclaims. "Oh, that's crazy," Rob responds.

It can be recalled that Rob expressed his desire to have a baby boy since he wanted to have the same "father and son" relationship just like what he had with his late dad. Either way, the 29-year old Kardashian is happy to have a girl.

"It's an emotional moment. 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," Rob says in a confessional. "I'm just happy that the baby's healthy and I'm gonna be super happy with a girl."

The doctor goes on to announce that the baby seems to be perfectly fine.

"That's a nice, normal heartbeat," the doctor tells Rob and Chyna. "It's regular and there's no problem with the beat of the baby's heart."

The little bundle of joy also seems to take after her mother as the doctor joked during the ultrasound.

"Look at it, she's putting her little booty right up at ya." To which Rob responded jokingly, "She better not be doing that!"

Blac Chyna also shared the good news on Instagram as she posted their daughter's first sonogram. Now, only one question remains: What will the newest Kardashian girl be named?!

Rob and Chyna previously revealed that they probably won't carry on the tradition of the K names in the family. Fans will have to wait and see.

"Rob & Chyna" airs every Sunday at 9 PM on E!
