Kourtney Kardashian 'Can't Fake It' with Tristan Thompson and Grills Him for Repeatedly Cheating on Khloé

In a preview for next week's episode of 'The Kardashians', Tristan Thompson also tells Kylie Jenner about his infidelity: "Everyone got affected differently, but I think you were affected the most"

Kourtney Kardashian Barker still doesn't fully trust Khloé Kardashian's ex Tristan Thompson.

In a preview for next week's episode of The Kardashians, Tristan, 32, appears to be taking steps to mend his relationships with Kourtney and Kylie Jenner after cheating on Khloé multiple times.

Before he can do so, Khloé, 39, warns her ex, "In this family, if you do something to one of us, it affects everyone."

Tristan is seemingly up for the challenge, asserting: "I'm in the place now where I can own up to the mistakes I made."

However, tensions appear to run high when the NBA player finally sits down with Kylie, 26, and Kourtney, 44.

"Tristan is coming over and I do feel a little nervous," Kylie says, before Tristan finally shows up and admits to the beauty mogul, "Everyone got affected differently, but I think you were affected the most."

In a confessional, Kourtney admits, "Tristan and I really have not connected and I just can't fake it."

When the two finally do meet, Kourtney asks Tristan if he feels anything after he cheats. "Disgusted," Tristan responds, which prompts Kourtney to ask, "So then why do you do it again?"

Kourtney's feelings about her sister's ex are no surprise to Kardashians fans. In last week's episode, she shared her unfiltered thoughts about the NBA player — and why her daughter Penelope Disick isn't a huge fan of him either.

"I feel like she gets it from me," Kourtney explained after asking her daughter — whom she shares with ex Scott Disick — if it was OK for Tristan to come over with Khloé. "I told her the first day of school, I was so triggered by him ... I know why, but I feel like we all brush it off and are fine, and then I was just so triggered and I was like, 'I just can't do it anymore.'"

The Poosh founder elaborated further in a confessional: "Tristan has made horrible decisions and choices with my sister. There's times when I'm so triggered by him I can't be around him and then theres times when I just let it go because we just want harmony and, you know, he's the father of my niece and nephew."

Though Khloé has a positive co-parenting relationship with Tristan, she told cameras that she didn't blame her 11-year-old niece for feeling the way she does.

"Where I am at with Tristan has nothing to do with what I expect my family members to do. If Penelope has feelings about Tristan, rightfully so. And good for you, girl," she said. "I want Penelope to have these feelings and I don’t wanna talk her out of them because I don’t want this behavior to be something that I'm validating or I'm justifying. I want her to know that how she feeling is the right way to feel. We should not accept someone treating us like this."

Khloé and Tristan began dating on and off in 2016. He cheated on her multiple times, including with Kylie's best friend Jordyn Woods just days before their daughter True was born while he and Khloé were still together.

Years later, they gave their romance another shot, but it was later revealed in December 2021 that Tristan had fathered a child with Maralee Nichols. At the time, Khloé and Tristan were secretly expecting their second child via surrogate.

Khloé officially ended their relationship months before the birth of their son Tatum in August 2022 and has since emphasized repeatedly that she has no intention of getting back together.
