Chyna and Kardashian opened up to PEOPLE for a September cover story on their excitement over being parents — and Kardashian’s likelihood for waterworks upon his baby girl’s arrival.

“Rob is going to cry for sure,” Chyna told PEOPLE in August.

“I’m going to be very happy,” said Kardashian. “If there are tears, they’re going to be tears of joy.”

The couple’s baby special will air Dec. 19 on E!
