Khloe Kardashian is allegedly “trying to pretend” Tristan Thompson's cheating footage “isn't happening”.

The celebrity couple's relationship has been dominating headlines for the past 12 hours, after a video of Tristan cheating in a New York City nightclub started circulating online.

In the video, the Cleveland Cavaliers basketball player was allegedly filmed at the PH-D Lounge in Manhattan, where he is seemingly very cosy with a woman named Stephanie Vizcaya, who reportedly accompanied him to his hotel room later that night.

TMZ also released a video of him making out with a different woman back in October just outside of a hookah lounge outside of  Washington D.C.

But Khloe, who is due to give birth to the couple’s first baby any minute now, is “trying to pretend it isn’t happening”, according to a source who spoke to Radar Online.

“Khloe is shutting everyone out right now and doesn’t want to listen to anyone.

“She is trying to pretend this isn’t happening and keeps saying that she must put the health of her unborn baby girl before these lies.

“When she spoke to her sisters earlier today, she assured them that this was all a big misunderstanding and that Tristan would be able to explain it.

“But with all the recent evidence that has just presented itself, no one knows what to do.”

Tristan and Khloe began dating in September 2016 when Tristan's now ex girlfriend Jordan Craig was still pregnant with Tristan's first child. Neither has confirmed if he met Khloe while still in a relationship with Jordan.
