Jenner apparently spoke to the rapper about repeatedly discussing the tape, which Kardashian made with her ex Ray J in 2003.
Reports say that Jenner confronted West, stating that he is "bragging about the tape in bad taste" and that Kim should be thought about because of her other accomplishments.
A source told RadarOnline: "Kris had stern words with Kanye when she saw that he said he would put Kim's sex tape on while romping with other women."
Jenner reportedly found West's confession to be a "disrespectful claim" and quickly told him to stop "bringing up the past".
Kardashian recently revealed that she believes the relationship with West is "permanent".
In the same week, it was reported that West had rapped about Kardashian's tape in his new song 'Clique': "Eat breakfast at Gucci / My girl a superstar all from a home movie."
