"But what about mom's peace?" asked Khloe in the KUWTK clip. "Who wants Mom’s peace? Because that's what matters. Do we care about Caitlyn's peace? When she's never cared about ours?
"We don't want our mum to be uncomfortable at her own party. And yes, it is mum’s party. She created it. I just don't know why anyone would want to put their mom through that. I think it just sucks."
While Caitlyn has remained close with daughters Kendall and Kylie, she has become more and more estranged from stepdaughters Kim, Khloé and Kourtney ever since her transition in 2015.
"It sucks. I made a big f***ing mistake, so what do I do?' Kim continued in the clip. "Do I disinvite Caitlyn?"
"This is what’s going to happen," Khloe said. "Just say, 'Hey Cait, I'm so sorry but I jumped the gun. I don't want my mom uncomfortable at her own party. I hope you can understand. There are no hard feelings.' Make it super nice and be there for mum, too, when we expect her to be there for us."
Later in the episode, Kim called Kris and told her she uninvited Caitlyn.
"I would never do that to Kendall and Kylie, just like I would never do it to you," Kris said. "I promise you, I’m fine. Just let it go. Vodka is my friend."
There's never a dull moment.
