Though Kris didn’t elaborate on the health scare in the Kardashians trailer, a source tells Life & Style, “Obviously this news about the tumor was terrifying.”

While the insider notes that “apparently the prognosis is okay, and she’s going to be fine,” it has been a wakeup call to the Kardashian family.

“You can never say never with these horrible situations, so she’s not out of the woods just yet, and it’s got everybody imploring her to slow down,” the source says. “The woman never takes day off, even when she’s on vacation she takes meetings and answers every email. If she goes somewhere and they don’t have WiFi it’s a disaster because she’s always got to work, she makes that her priority.”

While Kardashians fans will have to wait until the season premiere to learn more about the status of Kris’ health, the family matriarch appeared in good spirits at this year’s Met Gala, where she walked the Metropolitan Museum of Art’s iconic steps alongside boyfriend Corey in matching white ensembles.

Still, the source shares that Kris — who is also mom to Kim Kardashian, Kourtney Kardashian and Rob Kardashian — “admits she’s a workaholic and she has been for as long as anyone can remember” because “she lives for building the family brand.”

Adds the insider, “But this scare along with her heavy drinking and the burnout issues should be a wakeup call. Everyone’s warning her that if she doesn’t change her way, it could lead to something much worse.”
