Los Angeles - Khloe Kardashian is annoyed her mother Kris Jenner has been "dragged through the mud" by Caitlyn Jenner.
The 30-year-old reality star was seen being confronted by her stepparent over "tough texts" she sent her in the trailer for this weekend's episode of I Am Cait.
In the clip, which marks the first time Khloe has been seen on the former Olympian's show, Caitlyn said: "We haven't really gotten a chance to sit down and talk since you sent me all those tough texts."
Khloe replied: "Kim said that you said they were tough and Kim read all of them and she was like 'These really weren't that tough.'
"I just said 'We don't care what you're doing.' Meaning we don't care if you want to transition. We want to support you and be there for you.
"But, we don't think that that entails you speaking negatively about my mom.
"In our opinion, you don't even need to mention my mom...Let's focus on the actual cause here and let's not drag my mom through the mud."
Khloe went on to criticise Caitlyn for her conduct towards Kris, who she was married to for 22 years, insisting it would have a negative impact on their daughters, 19-year-old Kendall and 18-year-old Kylie.
She added: "I would think you would come from a place more of compassion, especially when you have two young daughters who are greatly affected by it."
Caitlyn, 65, seemed unimpressed by her stepdaughter's comments, insisting she "doesn't know" what she is talking about.
Khloe continued: "And that was really my premise for the text messages, and then when you try to tell me I don't know what I'm talking about..."
Caitlyn interrupted: "Because you don't know."
