Kim Kardashian is calling out her mom Kris Jenner for being "judgmental" and revealing one "frustrating" thing she does as a grandparent.

The SKIMS founder appeared on the November 12 episode of the What in the Winkler podcast where she opened up about how her mom judges Kardashian for the snacks she lets her kids — North, 11, Saint, 8, Chicago, 6, and Psalm, 5, who she shares with ex Kanye West — have but then go around and have the same sweet treats at her own house for her grandkids to enjoy, per People.

"This is the one really frustrating thing that my mom does," she said. "My mom is like the most judgmental when it comes to snacks and candy. Then her house has every candy, ice cream — it's like a kid's heaven."

The Kardashians star went on to share a recent example from when she and her family celebrated the momager's 69th birthday earlier this month.

"So she invites us over and then my son went into a freezer last night to get — it's her birthday, so she has cake — and he goes, 'I don't want cake, I want an ice cream instead,'" she said. When Jenner made a comment about her grandson eating the treat, Kardashian pointed out that Jenner is the one who had it in the first place. "My mom judges me like I'm the worst because I allowed them to have an ice cream that they had at her house."

Jenner is proud to be a grandmother of 13, and like many grandparents has spoiled the young ones with special gifts and sweet well wishes. Earlier this year, she also shared the backstory of the "cute" nickname her grandkids call her.
