WATCH: The Exact Moment Rob Kardashian Tells Blac Chyna He’s Diabetes-Free

Rob Kardashian has some big news for fiancée Blac Chyna, though she seems a little bit nervous about it.

In a new preview for an upcoming episode of Rob & Chyna, Kardashian reveals to his pregnant fiancée that he’s “completely free of diabetes.”

“I just met with Goglia, the nutritionist, and he just told me all of my numbers and I’m completely free of diabetes,” Rob says. “That’s like, the best news I’ve heard all year, literally.”

“What about us having a baby?” Chyna quips.

“That’s obviously in front of that,” Kardashian replies, laughing. “The baby is obviously the best news.”

Though Chyna is initially thrilled about the big health update, she starts to become anxious when her husband-to-be starts making plans to move out of their shared house.

“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. I’m trying to find us a house — like a house where you and me both love and are comfortable in. I’m just not comfortable here” he tells her before adding in a separate scene, “I’m going to prove to her that I’m back on track.”

However, it seems Kardashian has already fallen off the wagon. In recent photos, the 29-year-old appears to have gained all the weight back that he lost earlier this year. According to insiders, Kardashian packed on 50 lbs. in the last two months, clocking in at almost 300 lbs.

“Rob is slipping back into a dark place,” a source tells TMZ, adding that his family is “scared for his life.”

Last December, Kardashian was hospitalized after he fell ill and was diagnosed with diabetes.
