It's no secret tension between Kris and Caitlyn has been high thanks to claims the former Olympic athlete made in her new memoir, The Secrets of My Life; however, Kim has confirmed the two aren't talking at all.
And when asked by Andy Cohen on Sunday night's Watch What Happens Live episode whether there is a chance Kris will ever speak to Caitlyn again, Kim quickly replied, "Zero."
The 36-year-old mom of two, however, attempted to adjust her answer after having a second to think it through.
"One. No, I would say two. Two percent, and those are [Kendall Jenner and Kylie Jenner]," Kardashian said, citing her half-sisters as the reason. "So that's their percentage. All fair, I think."
Caitlyn and Kris split in 2013 after 22 years of marriage, and finalized their divorce in 2015 prior to Caitlyn publicly coming out as transgender in the summer of that year.
Kim discussed her mom's relationship with Caitlyn in late April, a couple of days after Caitlyn's book was released, during an appearance on The Ellen DeGeneres Show.
"My heart breaks for my mom, you know, because I feel like she's been through so much and [Caitlyn] is promoting this book and she's saying all these things," the Keeping Up with the Kardashians star told host Ellen DeGeneres. "I don't think it's necessary and I just feel like it's unfair, things aren't truthful."
One of Caitlyn's claims in her memoir is that 61-year-old Kris "made her suppress her true self" during their marriage, suggesting that Kris knew about her then-husband's feminine desires, according to Us Weekly. Caitlyn also called herself Kris' "punching bag" throughout that relationship.
"Caitlyn is not being honest?" Ellen asked Kim on her show about the book.
"No. Not with certain things about my mom, or other things," replied Kim, who hadn't spoken to Caitlyn in weeks at that time.
"I feel like it's taken a really long time for her to be honest with herself, so I don't expect her to be honest about my mom now. But it's just so hurtful. I wish her all the success in the world, um, but not at our expense."
