In the past, Grandma Kris Jenner lectured Kourtney on going against tradition and having a baby out of wedlock.

"You're going against every single thing that I believe in," Kris previously told Kourtney on Keeping Up with the Kardashians. "You grow up and you get married and you have babies."

But Kris was just as excited as her daughters and wrote, "YESSSSSSSSSS @KourtneyKardash is PREGNANT!!!!!!!!!! Wooohooo so excited and blessed!"

Maybe that's because Kourtney's wedding is on the way!
