The 31-year-old star finished shooting Tyler Perry’s The Marriage Counselor in Atlanta last weekend.
But Kardashian’s spokesperson denied the reports, saying: “there’s no truth to it”.
The reality star started filming on November 9, soon after she announced the end of her 72-day marriage to Kris Humphries and speculation started over whether the wedding was staged.
Kardashian’s casting in the movie has also angered Tyler Perry fans.
One wrote: “Personally, I am sick to death of her being glorified for nothing more than having sex on camera.
“She doesn’t need the money and she certainly doesn’t need any more attention. And, although I still support you, I won’t be contributing one dime to anything with K. Kardashian in it.”
Another comment wrote: “I urge you to not cast Kim in your movie, ‘The Marriage Counselor.’ Kim Kardashian has no respect for the sacred institution of marriage and treats it as if it’s a joke.”
Sources added that Kardashian kept a low profile on set and there were no threats to her safety.
Kardashian’s soon-to-be ex has hired a divorce lawyer and a source has said he “doesn’t want a war. He’s lying low.”
