The most exciting drama to keep up with. Kim Kardashian‘s relationship with Kourtney Kardashian hasn’t always been smooth sailing.

The Kardashian-Jenner clan, including Kris Jenner, Caitlyn Jenner, Khloé Kardashian, Rob Kardashian, Kendall Jenner, Kylie Jenner, and Kourtney and Kim Kardashian, skyrocketed to fame with the debut of “Keeping Up With the Kardashians” in 2007. This reality series provided an intimate look into their lives, showcasing their triumphs and tribulations both in their personal relationships and professional endeavors.

While the show portrayed the collective experiences of the family, Kim Kardashian has often been credited as a driving force behind their widespread success. In a 2016 interview with Editorialist magazine, Kim humorously debunked the notion of her mother Kris Jenner being the sole orchestrator of their careers, asserting her own role in guiding her siblings’ paths. However, Kourtney Kardashian playfully teased her sister’s self-assuredness during a memorable moment in the season 17 finale of “KUWTK” in December 2019. Dressed up as Kim for a family costume party, Kourtney jokingly claimed credit for initiating the family’s rise to fame, tongue-in-cheekly challenging Kim’s narrative.

The playful moment came one year after one of the siblings’ biggest arguments to date. During season 15, Kim and Kourtney clashed over scheduling for a family photo shoot as Kourtney prioritized spending time with her children.

“I’m leaving at 4 p.m. and I don’t care what anyone says,” Kourtney told Kim and Kris in the 2018 episode, to which the Selfish author fired back, “Get the f–k out of here, and go! No one wants you in the shoot.”

The feud between Kim and Kourtney Kardashian reached a boiling point during a heated exchange captured on “Keeping Up With the Kardashians.” Kim’s frustration with Kourtney’s perceived lack of business acumen led to a verbal altercation in which Kim criticized Kourtney’s contribution to the family’s empire, famously remarking, “She’s the least exciting to look at.”

Their disagreement over work ethic persisted over the years, with Kourtney contemplating leaving the reality TV spotlight altogether. Matters escalated in 2020 when their feud turned physical, prompting their brother Rob to draw comparisons to the confrontational reality show “Bad Girls Club” on Twitter.

Following the conclusion of “KUWTK” and the family’s transition to Hulu, Kourtney reflected on her relationship with Kim, acknowledging the intensity of their conflicts. She emphasized the importance of maintaining personal boundaries and protecting her energy, expressing a desire to distance herself from family drama.

Although their tensions appeared to subside, new conflicts arose during the third season of “The Kardashians.” A teaser for the show hinted at renewed discord between Kim and Kourtney, particularly regarding their differing allegiances to Dolce & Gabbana, suggesting that their family dynamic remains complex and occasionally contentious.

The Kourtney and Khloé Take Miami alum, meanwhile, claimed: “There’s no boundaries, there’s no respect.”

In a dramatic voiceover, Khloé appeared to remark on the family drama, saying, “The tension is brewing. How did we get here?”

“[Khloé and I] vibe a lot on making fun of Kim. And then when that was gone, Kim and Khloé were vibing and then I was the one who got ganged up on,” the Poosh founder said in a May 2023 episode of The Kardashians. “Kim could never be as funny as me, obviously. And we would all do anything for each other. [We] ride for each other until the end, but it is a different thing.”

2023

In a June 2023 episode of *The Kardashians*, Kourtney Kardashian expressed her feelings about Kim’s behavior at her wedding to Travis Barker. She accused Kim of not showing genuine happiness during the event, contrasting her apparent lack of enthusiasm with the positive reactions of others in attendance.

According to Kourtney, Kim failed to acknowledge the enjoyable atmosphere of the wedding and never sought her opinion on potentially using elements of the event for herself. Kourtney suggested that Kim’s behavior may have stemmed from subconscious envy, perceiving everything at the wedding as potential financial gain rather than appreciating the moment.

This perception led Kourtney to believe that Kim was “spiraling,” implying that her sister’s actions were indicative of deeper emotional issues. The episode highlighted the complexities of sibling dynamics and the impact of perceived slights on familial relationships.
