'I Say Jenner': Find Out The Reason Kris Jenner Refuses To Call Her Ex Caitlyn –– 'Momager' Opens Up About Surprising Habit

Kris Jenner said she can't call her ex by her new name Caitlyn Jenner, saying that she calls her by last name only.

The mother of reality TV's royal family was asked by Access Hollywood's Billy Bush, "Can you call Caitlyn, Caitlyn?"

"No -- I say 'Jenner,'" the sexy "Momager" responded, adding that "it's hard, you know, it's really, really hard" to make the adjustment in regards to her former spouse, who she was married to from 1991 until their separation two years ago.

The 59-year-old stressed that she's very supportive of her ex in her gender journey, but calling Caitlyn by her last name is a personal way of adjusting to her ex's significant life change.

"What I have realized in all of this is that everyone handles stuff a different way," Kris said. "No matter what it is, you know. We're all people. We all have different emotions."

The mother-of-six said that she's "getting to know" Caitlyn since the two have gradually mended fences after an initial falling-out over the harsh words they exchanged in the Vanity Fair issue in which Caitlyn premiered her new self to the world.
