Kim Kardashian and Kanye West may have already welcomed their fourth child, as sister Kourtney revealed that their surrogate went into labor yesterday.

In an appearance on Ellen, Kourtney surprised mom Kris Jenner by bringing six of the grandchildren to the show. Mason Disick, 10, Penelope Disick, 6, North West, 5, Reign Disick, 4, Saint West, 3 and Chicago West, 1, all appeared on Ellen's famous couch as Kris Jenner fought back tears.

Ellen revealed that Kim was originally slated to make the appearance but had to cancel last minute as the surrogate went into labor.

“So, my mom doesn’t even know this, but Kim’s surrogate went into labor, so she’s at the hospital,” Kourtney, 40, revealed.

“What! What are we doing here?!” Kris, 63, said.

Kourtney had a bit of a hard time making the announcement as a very enthusiastic Reign had quite a lot to say.

No word on the baby yet, but check out the adorable video below:
