The 29-year-old reality star and 28-year-old model revealed in a Facebook Live Q&A Wednesday that they're waiting to tie the knot until after the baby is born so Blac Chyna can "turn up" at the wedding.
"If it was up to Rob, literally, we would go tomorrow," the model said. "He wants to go there, but I'm like, 'We need to do it the traditional way.'"
"We would have been at the courthouse downtown a long, long time ago," Kardashian agreed. "[But] of course every woman deserves to have a beautiful wedding not when they're pregnant ... So we'll wait for the wedding."
"I want to turn up after. I want to turn up on my honeymoon and I want to turn up on you," Blac Chyna explained. "But I think next year, to kind of give you guys an idea. It's not going to be this year. I kind of want to get my body back."
Kardashian and Blac Chyna, who is already mom to son King with Tyga, got engaged in April. The couple announced they're expecting their first child the next month, and teased more babies to come in the interview.
"Rob wants me to have, like, four more or something like that," Blac Chyna said. "[Or] three more, so four total. Plus King, that's five."
Kardashian and Blac Chyna appeared to be on good terms following the first trailer for their E! series Rob & Chyna. The promo sees Blac Chyna blow up at the reality star and demand to know if he is texting other women.
