Now, the 28-year-old model is sharing the first sonogram of their daughter, taking to Instagram to post the photo for their fans.
"@robkardashian and I can't wait to meet our baby girl," Chyna captioned the black and white pic in which you can just barely make out the baby's face.
The couple also shared the news of their baby's gender by posting a video on Instagram.
"We having a girl ‼️‼️" Rob captioned the announcement. "Can't wait to see her."
Chyna shared the same video, writing simply, "It's a girl" with pink heart emojis.
Meanwhile, fans watched the pair find out the gender of their baby on Rob & Chyna Sunday during a filmed visit to the doctor. Though Rob was hoping for a little boy, he explained that he's just as excited for the princess.
"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 said in a confessional during the epsiode. "I'm just happy that the baby's healthy and I'm gonna be super happy with a girl."
Now the big question everyone keeps asking remains: What will the newest Kardashian girl be named?!
During a Facebook Live chat last month, one fan asked Rob and Chyna if they'll "carry on the tradition of the K names" in his family. Both of them answered the same: "Probably not."
Congrats again to the soon-to-be parents!
