Did someone just forget that he's about to become a daddy? Rob Kardashian gets caught up in the good news about his health on Rob & Chyna's Sunday, October 9, episode, as seen in a sneak peek.

The E! series' preview clip shows Kardashian, 29, telling pregnant fiancée Blac Chyna, 28, that he just got back from a checkup to get the latest on his battle with diabetes.

"I just met with Goglia, the nutritionist, and he just told me all of my numbers, and I'm completely free of diabetes," the Keeping Up With the Kardashians mainstay says. "That's the best news I've heard all year, literally."

However, a baffled Chyna replies, "What about us having a baby?" Oops! (The couple announced in April that they are expecting a little one later this year, and Us Weekly exclusively revealed that the pair are having a girl.)

Kardashian rethinks his superlative and backpedals a bit: "The baby's obviously the best news. That's of my life."

The Arthur George sock designer then points out that he'd like the makeup maven to move out of the home she shares with her roommate, Paige, and get a new pad with him. "I definitely think you and me are in a really good place right now, but I just don't see why we can't get on the same page," he says. "I'm trying to find us a house — a house [that] you and me both love and are comfortable in. I'm just not comfortable here."

Watch the awkward clip above. Rob & Chyna airs on E! Sundays at 9 p.m. ET.
