Rob Kardashian and Blac Chyna sure know how to keep a secret. Shortly after the two announced their engagement, they let the world know that they were also expecting a new addition to their family. As far as the baby's sex though? That much they've been pretty tight-lipped about - until now.
During last night's premiere of Rob & Chyna, Chyna and Rob visited a doctor's office to (finally) find out the sex of their baby.
"I'm pretty nervous. I'm excited," Rob said beforehand. "I really want a boy."
But as it turns out? Rob and Chyna are having a girl, and they both seem pretty pleased with the news. Watch the big reveal in the video below.
