Speaking of the baby, the couple revealed that they have indeed chosen their child's name, though they would not reveal what it is!
"I guarantee you, none of y'all will guess it," Rob teased. "It does not start with a 'K.'"
Meanwhile, Rob also took a moment to apologize to his sister, Kylie Jenner, while explaining all the family baby shower drama that took place on Twitter this week, that culminated with Rob publicly tweeting her phone number.
Rob added that these kinds of miscommunications are common in a family as big as his, and that everyone had moved past it, though he did add, "She definitely blocked me, and she didn't give me her new number."
"I'm sorry, Kylie, if you're listening," Rob apologized. "I love you!"
It's good that things appear to be on the mend with Rob and Chyna after their dramatic week. On Thursday, a source told ET, "Their relationship is not in a good place right now but they are working on it," adding that the chances of their reconciliation is "pretty high."
Then on Wednesday, the reality star Snapchatted several photos of himself in bed with his pregnant fiancee.
