The Good American co-founder, 38, slammed fans for speculating that the pair are back together in a comment on Instagram Wednesday, calling the whole thing “exhausting.”

“Stop pushing this narrative. It’s tiring,” Khloé added in response to a fan page screenshot from celebrity gossip account Deux Moi that read, “Kim supporting Tristan at the Lakers game… what is going on? 🫠.”

This followed a trip by Khloé’s sister Kim Kardashian and her daughter North West, 9, to the NBA playoffs, where they cheered on the Lakers center-forward and held up a DIY cardboard sign featuring 32-year-old Thompson’s name.

“Allegedly he’s back with Koko so maybe she’s soft launching the idea so everyone is prepared & doesn’t give Koko a hard time,” read the fansite’s speculation.

Addressing the claims, The Kardashians star shared a lengthy response in the comments section of the post.

Khloé Kardashian and Tristan Thompson’s Relationship Timeline

“I suppose you guys will continue the narrative you want regardless of what I say so what’s the point. It’s exhausting but I learned people will only understand to the level of their own perception. Most are stuck at believing the lies because it’s the narrative they want to fuel. Have fun….”

Khloé then noted that Kim, 42, was simply “supporting” Thompson at the game during a “difficult” period, perhaps alluding to the NBA star losing his mother Andrea in January.

“Some things are just as simple as they seem. A family member supporting another family member ESPECIALLY during a difficult time in life,” she wrote, before going on to compare Kim’s support to her close bond with her sister Kourtney Kardashian Barker’s ex Scott Disick. “Example….. just how I support Scott and will forever support him. He’s my brother,” she continued.

“It’s just not on an nba stage. Sad new world, If there’s no photos people think it really didn’t happen but yes, I see Scott often. Some things really are just as they are. ❤️.”

Khloé shares two children with Thompson — daughter True, 5, and a son who was born last August via surrogate. Thompson is also dad to son Prince, 6, who he shares with his ex Jordan Craig, and a son called Theo with Maralee Nichols, who arrived last January.

Last month a source told PEOPLE that Khloé was finding it hard to “shut the door on anything romantic” with Thompson.

“Khloé thinks Tristan is a great dad, which she’s grateful for,” an insider told PEOPLE. “That sometimes makes it harder to completely shut the door on anything romantic.”

“Khloé is supportive of Tristan joining the L.A. Lakers. She wants him to have a career,” a second source told PEOPLE. “Having Tristan on the road again concerns Khloé. This is when all the cheating happened in the past.”

The insider added that the on-again-off-again couple “became very close again” after Thompson’s mom died.
