THIS IS BONKERS.

Okay, so remember earlier this year when Tristan Thompson was caught cheating on Khloe Kardashian literal days before she gave birth to baby True? How could you forget?

Well, the Kardashian sisters found out the same way we did - the Internet - and it turns out all of their reactions were filmed live as it happened for Keeping Up With The Kardashians.

As per usual, Kim is the one that alerted her sisters of the news and everyone started, naturally, freaking out.

It then gets super Unreal on us all, with behind the scenes footage as Kim's interview is interrupted with the discovery of the news. "Khloe's gonna die," she says.

"The whole thing makes me disgusted," Kourtney said in her interview. Kendall chose not to mince words and said "What a f*cking idiot."

But, believe it or not, it was in fact Kylie who told Khloe about the devastating news.

"I didn't wanna hurt her feelings, but I felt like she should hear from one of us versus on the Internet," she said.

The sneak peek ends with Khloe's BFF, Malika, calling Kim and cutting straight to the chase: "What the f**k is that?"

It's a shame that the family, especially Khloe, has to relive this experience again but also we're definitely tuning in.
