Just hours after mom-to-be Khloe Kardashian posted a lovely Instagram photo with her baby's father, Tristan Thompson, footage has surfaced that apparently shows Thompson cheating on Kardashian...and Twitter isn't happy with the NBA star.

TMZ also posted footage from October 2017 in which Thompson seems to kiss a woman while another touches him aggressively.

Needless to say, Kardashian's fans were pissed, and let loose on Thompson on Twitter. Kardashian is nine months pregnant, and the couple first announced they were expecting a baby in December.

"That video of Tristan cheating on Khloe Kardashian is appalling. Them girls were CELEBRATING they knew they had just wrecked a home. What kind of fucking WOMAN celebrates that. Only a fucking cheap skank. I’m sad for Khloe," one fan wrote on Twitter, while another noted "I'm actually really hurt about this Tristan Thompson situation. Khloe finally gets pregnant after years of struggling and this is how the baby of her father treats her and embarrasses her LIVE during the masses?! BEFORE the baby is even born?! G2g. I'm sick."

Still, if there's one thing that isn't giving Kardashian any anxiety, it's the physical act of giving birth — she said on her app that witnessing members of her family deliver has significantly prepared her for the process.

“I've seen over eight births live and in person. Women were made to do this!” she said. “I read my apps every day and I ask my doctor if I have any questions...Of course I'm a little nervous to go into labor, but I'm trying to not overthink something that literally happens all the time."
