Kris Jenner Jay Leno - H 2013

The reality matriarch says her daughter decided on North West after the “Tonight Show” host brought up the name in an interview.

Late night comedians made plenty of jokes about Kim Kardashian and Kanye West naming their daughter North West. But could one of them have been responsible for it?

North’s grandmother, Kris Jenner, says Jay Leno played a pivotal -- if unintentional -- role in the naming.

During an appearance on NBC’s The Tonight Show on Friday, Leno played Jenner footage of his interview with Kardashian from March, in which he brought up an Internet rumor claiming North would be the baby’s name.

Kardashian denied the rumor, but according to Jenner, had second thoughts after taping the show.

“This is a true story, and I am not messing with you,” Jenner told Leno. “She called me and she goes, ‘You know what? Somebody had mentioned the name before. I  never really took it seriously. I didn’t think about it. And, Mom, after Jay brought it up, I think I want to name the baby North.’”

Jenner pointed to Leno and said, “I think you’re responsible,” to which Leno responded “so it’s my fault.”

Kardashian gave birth June 15.

Soon Jenner will go from talk show guest to talk show host when Kris begins a six-week trial run July 15 on five or more Fox stations. In a recent cover story for The Hollywood Reporter, she said she hopes she can be a “positive influence" for women.

"So many women give up in life when they get a little bit older," she told THR. "I want to be a positive influence. I want to come from a really good place. Some people are just lost, and maybe I can be an inspiration."
