Over the weekend, fans noticed that Kim is no longer following Tristan on Twitter and Instagram. Kim's decision came right around the time the Cleveland Cavaliers star took to Instagram for the first time since the cheating allegations broke to celebrate his team's victory on Sunday.
The Keeping Up With the Kardashians star appeared on Monday's Ellen DeGeneres Show, where the mother of three addressed the allegations that Thompson was cheating on Khloe in the weeks before she gave birth to their first child, daughter True.
"Like, I don't even know how to describe it," Kim told Ellen when asked for her opinion on the reports. "It's just so f**ked up."
"I kind of made this rule with my brother: if there's a baby involved, I'm going to keep it cute, keep it classy and not talk too bad," Kim added. "I'm going to try not to say anything negative, because one day, True is going to see this, and you know, it's so messed up."
Khloe welcomed her newborn daughter on April 12 in a hospital outside of Cleveland, Ohio.
