“For how long?” Kris asked.

“And nobody knows, so everyone in the audience don’t tell,” Kourtney explained while laughing.

While the full interview with the DeGeneres does not air until Friday, the host could not help but share a sneak peek the exciting news on her social media.

Before Kourtney came out and surprised her, Kris told DeGeneres and the audience — who are all pregnant with their first children — about her own experience with having babies.

“I loved being pregnant… that’s why I did it six times. You either love it or you hate it. Kim hated it,” Kris said.

“It’s either super uncomfortable or the best thing you’ve ever been through,” Kris continued. “Another human being is coming out of you… it’s a miracle!”

Kris also spoke about delivering daughterKhloé KardashianandKylie Jenner‘s children.

Just in case she wants to deliver Kim’s child, DeGeneres gave the momager blinged-out scrubs with her nickname “Lovey” written across the back. The scrubs were also equipped with a camera in the pocket to capture the special moment.

Just last week,fans were in a tizzyafter Kim shared a series of sweet texts from Kanye, who sent her a serene photo seemingly taken from inside their home.

The rapper, 41, followed up the snapshot with messages that read, “This is your life / Married with four kids / Get people out of jail / Cover of Vogue / Go to church every week with your family / Dreams come true.”

Understandably, followers immediately questioned whether the couple had welcomed their son — but Kim was quick to quash the rumors.

In January, PEOPLE confirmed the couple was expecting their fourth child,a son.
