Tristan Thompson allegedly cheated on pregnant Khloe Kardashian

Don’t Trist and tell.

Video from October surfaced Tuesday of Tristan Thompson hooking up with two women at a hookah lounge in Washington D.C. while girlfriend Khloe Kardashian was three months pregnant.

The black-and-white footage, acquired by TMZ, shows the Cleveland Cavaliers power forward canoodling with the women on a couch, making out with one of them while the other pulled his head into her chest.

Kardashian and Thompson announced the pregnancy in December, but rumors began circulating as early as September that the reality star was expecting. The video was taken in October, according to TMZ.

The gossip site also spotted the NBA star entering his New York hotel Sunday morning with a female companion, who left with an overnight bag.

Kardashian is expected to give birth to her first child, a daughter, any day now and is reportedly waiting out the pre-labor in Cleveland.

Her first husband, Lamar Odom, cheated on her throughout their marriage, she revealed after the split.

Thompson’s ex-girlfriend, Jordan Craig, gave birth to the couple’s son in December 2016, four months after he and Kardashian were set up on a blind date.
