Kim Kardashian is unhappy with Caitlyn Jenner for her comments about her former wife Kris Jenner.

During Sunday's (16 August) episode of I Am Cait, the 34-year-old reality star lashed out at the former Olympic athlete for her comments on Kris Jenner during her Vanity Fair interview.

"You said, 'Had Kris been accepting to who I am, we still would be together.' And that's the most unfair thing in the world to say," Kim yells at Caitlyn. "You don't look at it that way, but my mom does."

She also defended sister Khloe who slammed Cait for her insensitive remark about her mother.

"Khloé sees my mom upset and so she gets defensive," the Keeping Up With the Kardashian star told Jenner.

The transgender celebrity hit back saying "and she doesn't know anything about my side of the story".

"But, that's what kids do. She is gonna get defensive," the pregnant celebrity retorts, adding that the I am Cait star's views on her daughters post her transition have been elusive.

"I read the Vanity Fair as well, and I think there are some things that you said that you might not realise are hurtful. You said Kendall and Kylie Jenner were a distraction, and so when they read that, they're gonna think... I don't think they'll quite understand that."

In last week's episode, Khloe had a heated argument with the 65-year-old Olympian and asked her "not to drag my mom through the mud".
