The reality star also opens up about her relationship with Tristan Thompson in 'KUWTK's 10th Anniversary Special.
The Kardashian/Jenner family talks about it all, good and bad, on their upcoming 10th Anniversary Special,
In a new promo released on Thursday, the family recalls Lamar Odom's 2015 hospitalization, during which he was in a coma and was placed on life support after being found unconscious at a brothel in Nevada.
"I landed in London and the first text that popped into my phone was from Kim and it had said that Lamar passed away. And I immediately started sobbing on the plane," Kendall said of her hardest day to work over the last 10 years. "Then I got the next text came through, saying, 'OK, actually, he's OK, but he's not doing well.' So that's why I was so upset, because I wanted to be there to say goodbye."
"On the plane, they said he died," shared Khloe, who put her divorce from Odom on hold to care for him after his hospitalization. "Someone faked it."
"I was screaming," she continued. "But to think, and to go through the motions as if someone has passed away is the most traumatic thing to do, and then to know they're really alive... it was too many emotions, I think, for any of us to handle."
Khloe and Lamar's divorce was finalized in December 2016, months after she started dating Cleveland Cavaliers star Tristan Thompson.
"I kind of have a type, I guess," Khloe confessed in another promo. "I don't know what that is, but I was put on a blind date with Tristan, and that's how I met Tristan."
"I was at the Bel-Air Hotel. He came to the dinner... I had a bunch of people and Brandon Jennings brought him, and we just connected," Khloe recalled. "It's a serious relationship."
"It's a level five," Kourtney interjected. "[Out of] six."
