During the latest episode of The Kardashians, which debuted on Hulu on Thursday, Kourtney, 44, held nothing back when confronting Tristan about his history of infidelity.

The Lemme founder maintained that she had no anger toward him but added that she was struggling to understand why he continually cheated on Khloe, 39.

Tristan confessed: “When I cheat, I feel disgusted the next day. I was literally just cheating just for a feeling.

“It came down to not knowing how to love.”

The NBA player continued: “With therapy, I realized my childhood upbringing, how my dad was treating my mom. As a kid when you see that, the trauma you have is because you can’t protect your mom. So you numb your emotions of feeling sad.

“It’s my defense mechanism.”

Tristan went on to claim that his late mother, Andrea Thompson, had to numb her feelings to be there for him and her siblings.

He said on The Kardashians that he “never knew how to feel pain” for this reason, noting that his mom was “always happy” during his childhood.

Tristan said: ‘I’ve never seen a man treat a woman good. I’ve never seen a man not cheat on a woman. I’ve never seen a good husband. I’ve made a mistake.”

Kourtney chimed in, correcting him by saying he’s actually made “multiple” mistakes before asking: “What do you think the mistake is?”

The father of Khloe’s two children replied: “The mistake is I cheated. And if I would have told Khloe before hand instead of her being blindsided, maybe we could have figured it out together.”

The Good American founder’s older sister replied: “You’re talking about your mom not putting herself first. Do you think Khloe needs to put herself first so you don’t stand a chance?”

She then said blankly: “I don’t think you deserve Khloe. Or the actions that you’ve done is something she deserves.”

Tristan looked back at her, seemingly overcome with emotion as the episode came to an end.

STANDING HER GROUND

On X, formerly Twitter, fans praised Kourtney for defending Khloe.

One viewer posted: “The way Kourtney ate Tristan up? He brought up all his childhood trauma and Kourtney asked him where the hell Khloe fits in in that.”

“Knew Kourtney meant business when she whipped out that notebook,” a second Kardashians fan commented.

A third reacted with: “Kourtney ate him up with that “if you think about your mom and that she should have chosen herself, don’t you think of khloe and that she needs to choose herself and not let you stand a chance?” Then the immediate shut down when he tried to talk out of it? NOPE!!”

Someone else defended Kourtney saying: “Kourtney was absolutely right in what she said to Tristan and she handled it so elegantly. Every single one of them should’ve had this to say and more. Idek how he’s getting all this screen time and on top of that he wants forgiveness?! Or even worse Khloe back??”

FAMILY FIRST

Kourtney isn’t the only member of the Kardashian family to confront Tristan over his cheating.

The basketball player cheated on Khloe several times, fathering a child with one of his many mistresses, Maralee Nichols.

A preview for The Kardashians was posted online, teasing a tense sit-down between Kylie and Tristan.

In a voice-over, she said: “Tristan is coming over and I do feel a little nervous.”

A subsequent scene showed Tristan sitting across from the Khy founder on a couch in her backyard.

She was dressed in a red bodysuit and jeans while wearing subtle makeup and her hair down around her shoulders.

Tristan moved his arms around as he said: “Everyone got affected a little differently, you know, but I think you were affected the most.”

Cameras then cut to Kourtney and Tristan hugging ahead of snippets of the conversation that aired out in Thursday’s episode.
