Jenner, 58, revealed she thought if her daughters did not start a family soon, she would not get to play the role of a grandmother, reported E! Online.
"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," said Jenner, whose daughter Kourtney Kardashian is expecting her third child.
Jenner said she is beyond excited about Kourtney's pregnancy and joked that her kids are on fire. "But they are on fire right now. You can stop, I was just kidding," she said.
Jenner's another daughter Kim has a one-year-old daughter and Kourtney is mother of Mason, 4, and 23-months old Penelope.
