Khloe tries to mediate between the two, but it doesn't go as planned.
Kourtney Kardashian has drama with her mama.
In an exclusive sneak peek at Sunday's new episode of "Keeping Up with the Kardashians," the reality TV star squares off against mom Kris Jenner, as sister Khloe Kardashian tries to mediate.
"For some reason, you do not give mom the benefit of the doubt, ever, from your childhood and it's really unfair," Khloe says, appearing to be on Kris' side. "You only remember with Todd, or this or that."
Todd would be Todd Waterman, a man who Jenner admitted to having an affair with in 1989 while married to Robert Kardashian Sr.
"I don't sit there and dwell about Todd," says Kourtney, before Kris tells her that she has "her own Todd right now." That doesn't sit well with Kourtney, who doesn't see then-boyfriend Younes Bendjima that way.
"No, I actually don't. I'm actually not married and I'm not having an affair," she shoots back. "You can't compare one to the other, it's absolutely not true."

Kanye West Publicly Shares Text Conversation with Caitlyn Jenner -- After Kim Cut Off All Relations
View StoryThe clip ends with Khloe telling her sister, "Sometimes our memories get a little warped by our age, but don't be so hard on your mom," as Kourtney says the root of this issue may be unfixable.
Kris revealed her affair in her 2011 memoir, "Kris Jenner … And All Things Kardashian," an affair she called "one of my biggest regrets in life." Speaking with Harvey Levin on "OBJECTified," she added, "But when you're in something, sometimes people think the grass is always greener and that was like what I think I went through at some point."
She actually met up with Waterman during a 2012 episode of "KUWTK," while married to Caitlyn Jenner. She caught flack from her family at the time, but said the meeting only reaffirmed her belief she "made the right decision" by picking Jenner.
