Khloé Kardashian confronts Caitlyn Jenner about Kris

As fans of the Kardashians know, Khloé Kardashian isn't one to shy away from speaking her mind.

In a preview for Sunday's I Am Cait, which marks the first time we've seen the 31-year-old star and parent Caitlyn Jenner on camera together, the Keeping Up With the Kardashians stunner confronts her parent over comments she made about ex Kris Jenner, whom she was previously married to, prior to her transition, for 22 years.

"We haven't really gotten a chance to talk since you sent me all those tough texts," Caitlyn says while wearing a pretty blue sweater, her eyes filled with emotion.

"Kim [Kardashian] said that you said they were tough and Kim read all of them and she was like ‘these really weren't that tough,'" Khloé counters. "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."

She continued, "But, we don't think that that entails you speaking negatively about my mom [Kris Jenner]," adding, "In our opinion, you don't even need to mention my mom...let's not drag my mom through the mud."
