Coming out with six of Kris' grandchildren -- including Kourt's and Kim's kids -- the "KUWTK" star told her mom, "Kim's surrogate went into labor."
"So, she's at the hospital," she continues. "I have to go to have a baby."
Kris' jaw literally dropped to the floor in shock.
As The Blast reported, Kim and Kanye's surrogate was due this month. They are expecting a boy and he will join his siblings -- North, 5, Saint, 3, and Chicago, 1.
