Surveillance video surfaced Tuesday night of Thompson at a hookah lounge in Washington, DC with two women. The video is from October when the Kardashian was about three months pregnant.
The Keeping Up With the Kardashians star is currently nine months pregnant and due to give birth to her and Thompson's first child together, a baby girl, any day now.
In the footage, Thompson is seen sitting on a couch with the two women. The athlete appears to kiss Marie, who is sitting on the left, and grabs her hand.
Thompson also puts his face in the second woman's chest as she laughs. Marie then reaches over and rubs her hand across Thompson's crotch.
Not much is known about Marie except that she has celebrity friends. Last month, she was seen partying with Chris Brown in Miami.
The video, filmed while the group was outside on a balcony, drew criticism when Brown was seen grabbing a woman's neck. Brown said he was just playing around. TMZ reports that Marie also said the incident was nothing but horseplay.
Kardashian, 33, and Thompson, 27, have remained silent on the cheating scandal, but one woman who is claiming she also had an affair with Thompson has been speaking out on social media.
A woman by the name of Stephanie posted several raunchy text messages late Tuesday night she claims are between her and the Cleveland Cavaliers player.
In one message, the basketball player allegedly writes: "I would pull ya hair and kiss you then rip ya clothes off".
Stephanie, who goes by the name @ms.stephaniee on Instagram, also shared a sex tape she alleges is of her and Thompson. Not long after leaking the X-rated video Stephanie wrote in an Instagram story post that she is pregnant, possibly by Thompson.
"I'm pregnant too since everything out here," she wrote.
Stephanie is believed to be the second woman seen with Thompson at the DC lounge.
Thompson's cheating scandal started early Tuesday when the DailyMail.com exclusively reported that the 27-year-old athlete was seen kissing a woman Saturday night at the Penthouse at Dream Downtown in New York.
Video from inside the club shows Thompson and the woman, identified as 28-year-old Lani Blair, getting cozy and making out. They were later seen entering the Four Seasons hotel Thompson was staying at.
On Sunday night, the pair was caught on video leaving the hotel and heading to the Soho House, a private member's only club in Manhattan. Blair was carrying an overnight bag and wearing the same outfit she had on the night before.
They returned to the hotel around 5am on Monday. Thompson was seen in video talking on what appears to be Blair's phone and furtively looking around before walking into the hotel, while also carrying a bottle of water and his own phone in his hands.
The two then spent some time hanging out in the lobby while Thompson continued to speak on the phone.
Later that night, Thompson headed off to work as the Cleveland Cavaliers took on the New York Knicks on Monday.
At around 8pm that night, almost 48 hours after the two were first seen kissing at a club downtown, Blair was seen leaving the hotel in the same outfit but also carrying a Louis Vuitton bag.
