Kim took to Twitter with a response to 2cool2blog's comment on a TMZ video showing Khloe posing for photographers at an event for fashion retailer Pretty Little Thing in Los Angeles on Wednesday.
2cool2blog wrote , "If someone cheats on you publicly. Yall going outside the next day?"
In response, Kim tweeted that Khloe had agreed to appear at the event before the cheating reports occurred and she was fulfilling her commitment.
"Would you prefer she lose the [money] too? A single mom has to work too boo! This was a professional commitment planned far in advance," Kim responded , "and you better believe she is not waiting on anyone to pay her bills or provide for her daughter."
The veracity of the reports was seemingly confirmed as Khloe's close friends began commenting on the Hollywood Unlocked post . Malika Haqq, who fans would recognize by her many appearances on E!'s "Keeping Up With the Kardashians, wrote, "STRONG FACTS." That was followed by more comments and likes by people close to the Kardashian family, including publicist Tracy Romulus and friend Larsa Pippen. Khloe herself commented with yelling emojis.
Representatives for Khloe and Tristan didn't immediately respond to INSIDER's requests for comment.
This isn't the first time Thompson has been accused of cheating. While Khloe was preparing to give birth to their baby girl, Stormi, in Cleveland, Thompson was hit with multiple cheating allegations. The Kardashians later confirmed these reports .
