The Kardashian clan received false information on the day Khloe's ex-husband Lamar Odom overdosed.

The women revealed in a clip from the upcoming Keeping Up With the Kardashians' 10th anniversary special that they were first told Lamar had died the day he was rushed to the hospital in October 2015.

'I was screaming,' Khloe revealed during the interview with executive producer Ryan Seacrest.

The whole mistake started with Kim Kardashian who admitted she was given the wrong information and started texting her family.

'Someone made a fake account and emailed me with the wrong information,' she says.

Kendall Jenner recalled being on a flight from Hong Kong to London when she landed to the text from Kim.

 'It had said Lamar passed away,' Kendall said. 'And I immediately started sobbing on the plane. Then I got the next text came through, saying, 'Actually he's okay, he's alive but he's not doing well.' So that's why I was so upset, because I wanted to be there to be able to say goodbye.'

Khloe added: '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.'

Lamar was rushed to the hospital after he was found unconscious in a Nevada brothel on October 13, 2015.

He spent four days in a coma with news seemingly worsening and Khloe was by his side for the entire ordeal although they had both signed their divorce papers just months before in June.
