Tristan Thompson has seemingly done Khloe Kardashian wrong -- in a big way. Not only was he recently caught kissing a mystery woman at a nightclub in New York City on Saturday night, he also reportedly took that woman back to his hotel room for a late-night rendezvous on Sunday morning.

After the Daily Mail's initial report on April 10, which included video and photos of Thompson chatting with a brunette woman before appearing to make out with the unnamed lady [VIDEO], TMZ shared video footage of the moments that seemingly followed the couple's nightclub outing.

According to TMZ, the video was filmed around 5:00 a.m. on Sunday morning, hours after Tristan Thompson and the woman were seen getting cozy with one another at the PH-D Lounge. As the outlet explained, Thompson is staying at the Four Seasons hotel along with the rest of the Cleveland Cavaliers team.

Following their alleged rendezvous at the hotel, Tristan Thompson's mystery woman was seen making her way out of the venue with a Louis Vuitton overnight bag, which seemed to suggest she had spent more than just a few hours with the athlete.

Khloe Kardashian is ready to give birth any day now

Since the start of her romance with Thompson nearly two years ago, Khloe Kardashian has been spotted out and about in Cleveland, Ohio on numerous occasions and has expressed many times that she enjoys being in town away from the paparazzi.

That said, she's likely not doing too well at the moment as she prepares to welcome the child of her potentially cheating boyfriend.

Adding insult to injury when it comes to the recent allegations regarding Thompson's NYC outing is the fact that TMZ also shared video footage of Thompson taken in October of last year, when Kardashian was three-months-pregnant, which featured the athlete getting frisky with two women at the same time. As the outlet explained with the clip, the video was shot at a hookah lounge [VIDEO] near Washington D.C. and showcased Thompson as he made out with one of the women and motorboated the chest of another. Thompson also had one of the women feel his private part in the shocking clip.
