Kris Jenner says she once feared she would never be a grandmother.

The 'Keeping Up with the Kardashians' matriarch is "beyond excited" that her eldest daughter Kourtney Kardashian is expecting her third child because she adores her all her grandchildren.

Kourtney already has two kids -- Mason, four, and Penelope, two -- with her partner Scott Disick. Jenner's second daughter, Kim Kardashian, has 12-month-old daughter North.

Jenner told Giuliana Rancic on 'Beyond Candid': "Truth be told, there was a couple years ago where I thought if these kids don't get started, they're not gonna have any kids. I'm not gonna have any grandchildren.

"But they are on fire right now. You can stop, I was just kidding," Jenner said jokingly before adding: "No, no, the more the merrier around here."

Jenner -- a mother of six, who also has daughter Khloe and son Rob with ex-husband Robert Kardashian and daughters Kendall and Kylie with estranged spouse Bruce Jenner -- thinks being a grandmother is "fabulous" and she is enjoying the new stage in her life.

The 58-year-old star added: "I think that this is probably such an amazing time in my life and how it feels to be a grandmother, it's like nothing other than I could explain. It's just fabulous."
