Big news for Rob Kardashian and Blac Chyna! The couple announced that Chyna is expecting a girl during the season premiere of their new E! reality show Rob & Chyna Sunday night. The announcement came during a doctor's appointment when the ultrasound technician asked if they'd like to find out the gender of their little one.

"I'm pretty nervous. I'm excited," Rob admits before the big reveal. "I really want a boy."

"You are having ... a girl!" the doctor announces before the camera pans to the couple's shocked faces.

It's 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."
