Sources close to the Kardashians confirm to The Blast, Khloé ended things with the Cleveland Cavaliers star after finding out he had a romantic tryst with Jordyn Woods.
Hollywood Unlocked, who first broke the story, claims Thompson threw a house party in Los Angeles attended by Woods, and the two allegedly got very cozy. The 21-year-old allegedly stayed at Thompson's house until 7 AM.
Sources close to the Kardashian family tell us the situation is "sad," and it's unclear what Woods' relationship with Kylie and the rest of the family will be now that the hookup is out in the open.
Woods has been a staple of the Kardashian/Jenner family for years, and is regularly featured on "KUWTK." She's also modeled jeans for Khloé's Good American line, and also has a cosmetics collection with Kylie Jenner.
Hollywood Unlocked founder Jason Lee also spoke about the story on Instagram, and described the hookup at the party, that his employee witnessed. To top it off, Khloé actually liked the post!
Khloé's BFF, Malika Haqq, also publicly backed the story about Tristan's alleged cheating, and commented, "STRONG FACTS."
Fans of the reality stars are already dragging Woods over the accusations, and many messages have labeled her a "homewrecker." To be fair, Thompson and Kardashian have had many problems over the years, but Woods probably didn't help the situation.
She also apparently forgot the golden rule about relationships and business -- "Don't dip your pen in the company ink."
