Kris Jenner Surprised by Kourtney Kardashian’s Third Pregnancy (VIDEO)

With six kids of her own, it’s clear that Kris Jenner knows a thing or two about the birds and the bees. However, that didn’t keep the Kardashian matriarch from feeling more than a bit surprised when eldest daughter Kourtney Kardashian announced she was pregnant once again.

Kris recently sat down with E! host Giuliana Rancic to discuss her upcoming cookbook and how her ever-expanding family is feeling about the addition of one more kid to the mix. The Keeping Up With the Kardashians star says that, while Kourtney’s pregnancy was a surprise to everyone, she’s “beyond excited” to have another grandchild.

Though she’s become a grandmother many times over in the past few years, Kris says she was initially worried that her kids might not be the reproducing kind.

“A couple years ago, I thought, ‘If these kids don’t get started, they’re not going to have any kids — I’m not going to have any grandkids.’ But they are on fire right now … the more, the merrier around here.”

Kris may not seem like your traditional cookies and Christmas sweaters kind of grandma, but she says she truly relishes the role.

“It’s like nothing other on earth that I can explain,” says Kris. “It’s just fabulous.”
