The Kardashian sisters are once again at odds!
In a new sneak peek clip for Sunday's episode of Keeping Up With the Kardashians, Kim and Khloe Kardashian ambush their older sister, Kourtney, at a private residence where they think she's meeting a man.
"I'm not literally dating anybody," an angry Kourtney says.
"But we don't know, 'cause we don't know anything about you," Khloe fires back.
"What if I actually was? Then what? Like, you bring the cameras here?" Kourtney says. "It's so disrespectful. If I have boundaries, respect them. Just because you like to show every single thing."
Khloe notes that she doesn't "like to" share so much of her life, but adds, "It's our job."
Kourtney disagrees with this sentiment, but she doesn't find an ally in Kim. In an aside interview, Kim breaks down her and Khloe's beef with their older sister.
"Our job is being open and honest and sharing ourselves, and it just seems like, for the past few years now, Kourtney hasn't really been open about her personal life on camera," Kim says. "So all of the days that Kourtney isn't filming, Khloe and I are picking up the slack and having to share more. Because if we're not sharing our lives, then what is the show?"
Khloe doesn't appreciate Kourtney's diminished involvement in the family's reality series and tells her as much.
"You don't give anything. You coast? You think it's fair that you just coast through life?" Khloe accuses.
"What's important for you to share [isn't for me]," Kourtney says. "I said I would not share my relationships. That's it."
Kourtney later expresses her own frustrations in an aside interview, saying, "If they wanted privacy, I would never follow them or expose them."
Kourtney's ups and downs with her ex and the father of her children, Scott Disick, have previously played out on the show, with Scott still being a main part of many storylines. Her ex-boyfriend, Younes Bendjima, also appeared on the show prior to their split.
Kourtney has been very candid about not necessarily wanting to stay on the family's show. Last month, she spoke with ET about stepping back from her involvement on KUWTK.
"I just decided to spend more time as a mom and put more of my energy there," the mother of three said at the time. "But I'm not saying goodbye. I think you'll have to see more of it on the new season, season 18. It isn't airing yet but it's being filmed."
Keeping Up With the Kardashians airs Sundays at 9 p.m. ET on E!
