And while the occasion should have been one filled with joy and happiness, Khloe's was tainted by the news that her baby-daddy, Tristan Thompson, was cheating on her.
Now, in a new clip for the upcoming episode, we see exactly how it all played out when Kris and Kim rush to Khloe's side.
“I just moved the plane up and I think she’s in labor,” Kris tells Kim and Kourtney. She adds: “I knew we should’ve gone last night, I knew it.”
As Kris focuses on getting to Cleveland ASAP, Kim cancels on her high school reunion so she can rush to Khloe with Kris.
“You know, when there’s something crazy that goes on in our family, we just always drop everything that we’re doing and go be supportive to them,” Kim says. “I obviously wanted to go to my reunion and I wanted to make both work, but since my reunion is in two days it’s like game over, it doesn’t matter. I’m gonna go to Cleveland and be there for her.”
We can't wait to see how it all plays out!
