How Khloe Kardashian's sisters reacted for the first time to Tristan Thompson's misleading scandal – and to whom Khloe told

Khloe Kardashian's sisters are about to learn about Tristan Thompson's cheating scandal.

In! A preview of the new Sunday edition The amazing Kardashian familyKhloe's sisters discover for the first time online that Tristan was seen arguing with another girl just before the birth of their 6-month-old daughter, True.

In the clip, Kendall Jenner, Scott Disick, Kim Kardashian West, Kourtney Kardashian and Kylie Jenner all react to the report that the NBA pro was unfaithful to Khloe.

Kendall is in the car with Scott when she gasps out loud in front of a message that she has received from Kim. "Stop it! Bro, it's pretty serious, is not it," exclaims Scott, before wondering if it's "for sure, for sure."

"I do not know, that's what I'm trying to find," says Kendall.

Later, Kendall reads aloud some of the sources reporting the incident. "The woman who filmed the clip said," I was there and he was on the table next to us with a group of friends. Everyone watched them do it many times, "she says.

"I'm in shock right now. I do not even know what to say, "says Kendall. "What an imbecile! It's an unhealthy joke … Oh my God, I'm going to cry for her.

Meanwhile, Kim was on the set for the show when she heard the news. In the clip, she fixes her phone and asks everyone to hold on, before saying "yuck".

"There is a video of Tristan chatting with a girl last night," reveals Kim to the cameras. "Khloe will die."

Kourtney seems to be crossing her house as she digests information. "I mean, I can not even imagine being in Khloe's place," she says in the confessional. "How all of this seems carefree. It's really shocking and obviously heartbreaking. All this disgusts me.

The sisters soon learned that their youngest member, Kylie, had sent the article to Khloe.

"As I call Khloe?" Wonders Kim. "… she will literally get to work for that."

"Oh no," Kendall told Scott. "She knows it, but she does not answer the texts."

For Kylie, it was important to say it herself, so she would not discover it online.

"Nobody had the courage to tell Khloe because we knew that she would soon be giving birth, we did not want to stress her, but we knew it was the good thing to do, "Kylie, who was putting on makeup when she heard the news, said in the confessional. "So I told Khloe. I did not want to hurt her, but I felt like she should hear from one of us about the Internet. "

The new clip arrives a few days after a source told us that Khloe had returned to Cleveland in Ohio with Tristan – where he plays for the Cleveland Cavaliers – after initially putting him on hold.

"Khloe and Tristan are still working on some things, but know what they decide to do from the front, it will be best for their daughter, True," said the source. "Khloe does not know how long she will stay in Cleveland and could come back for her mother, Kris [Jenner’s]birthday next week, but I'm not sure. A lot depends on how things are going with her and Tristan. "

While in Cleveland, Khloe was a regular at Tristan's match.

The move is a bit of a surprise. Last month, a source told Khloe that Khloe did not know if she would return to Cleveland, largely because she had "had a hard time" reliving the scandal by watching this season KUWTK.

"Even though she worked to overcome the grief, the reminder recalls some of these emotions," said the source. "Khloe will probably return to Cleveland, but for the moment, there is no official date."

Despite the current uncertainty in their relationship, Khloe and Tristan spent Halloween with True, which they dressed in pink flamingo.
