In the sneak peek, the mom of two, 35, has a heart-to-heart with Jenner, 66, in NYC. The conversation went down ahead of Kanye West's Yeezy Season 3 show in February.
"Have you talked to Khloé at all?" Kardashian asks.
Jenner replies: "She hasn't been talking to me lately."
As seen in last week's episode, Jenner wasn't thrilled with Khloé, 31, speaking about her transition during The Howard Stern Show in January.
"We felt betrayed because more businesspeople [knew] … We felt so, like, what the f–k! We've been asking you, and why do people know?" Khloé told Stern at the time. In response, Jenner sent Khloé nasty text messages.
Following the icy exchange, Jenner and Khloé would next meet at West's show. The event was the first time Khloé's estranged husband, Lamar Odom, made a public appearance since his hospitalization.
"This is a really big week. Lamar is already dealing with the pressure of being in an environment where there's a lot of people, and this might be really difficult for him. And Khloé and Caitlyn are kind of on the outs," Kim says in a confessional in the preview clip. "So, everyone has to put our differences aside for this week and just be cool."
KUWTK airs Sundays on E! at 9 p.m. ET.
