The siblings have argued over everything from birthday parties to business deals.
Here’s everything it’s crucial that you know about their relationship.
The trip started off fun but soon Kim suffered what she regarded as a major crisis.
After Humphries playfullytossed her in the water, one of her expensive diamond earrings came off of her ear.
A shocked Kim immediately broke into sobs as she realized it might be gone for good.
“Kim, there’s people that are dying,” she bluntly told her sister.
Kim didn’t take too kindly to her sister’s nonchalant attitude and explained the worth of the earrings.
“Anyone would be annoyed, I work really hard and I bought these,” sheexplainedto her mom.
“This is the most expensive thing I’ve ever bought.”
She further explained the importance of the $75,000 earrings in 2017 to E!
Nevertheless, she added, “Yes, I see Kourtney’s point now.”
All the s**t I’ve done for her?'"
she angrily told Kourtney.
I bought her a f**king career!'"
Those harsh words from Kim obviously didn’t do much to persuade Kourtney into changing her mind.
However, Kourtney did eventually come around and appeared in the app.
While gearing for a family Christmas card, the sisters began bickering over the schedule.
Kourtney had requested that the shoot end at a certain so she can return home.
Kim, who had a business meeting scheduled for that time, found it difficult to accommodate those demands.
As the cameras rolled, thesisters began arguingand things quickly escalated.
After Kourtney suggested Kim simply reschedule her business meetings, Kim grew irate.
Kris Jenner made a futile attempt to deal with the disagreement, but not before Kourtney stormed off.
As she made her exit, Kim threw in one last hurtful jab her way.
“She’s the least exciting to look at,” said Kim.
Still hurt over the argument, Kourtneylater called Khloein tears.
She explained that she’s prioritizing being a mother over work obligations.
After another argument, Kourtney decided toskip Kim’s baby shower.
This, of course, upset Kourtney, who accused them of not respecting her boundaries.
Their argument led Kim and Khloe to ponder Kourtney’s role on the show.
The sisters eventhreaten to fire Kourtney, which obviously didn’t go over well.
After FaceTiming her, they let it be known that they were close to firing her.
Kourtney broke down in tears and later texted her sisters that she didn’t appreciate it.
The sisters even phoned momager Kris Jenner to voice their displeasure with Kourtney.
They argued that she wasn’t pressuring Kourtney enough to show her life on the show.
“Let’s show [Kourtney],” Kim said.
The Poosh founder was turning 40 and planned a party for the occasion.
As seen onthe show, she showed Khloe her birthday dress and asked for her opinion.
After seeing the dress, Khloe suggested they phone Kim.
“I don’t know if I trust [Kim’s] opinion the most,” Kourtney joked.
“We have completely different looks,” she said.
“I’m not trying to copy your styles.”
Kourtney further explained that they often wear the same designer brands.
The back and forth escalated via text messages with both sisters hurling names at each other.
Kim recounted the fight to their mother and admitted she called Kourtney a “fake humanitarian.”
When it comes tothrowing a birthday bashfor their kids, they love going all out.
From the festive themes to the star-studded guest list, their parties are nothing short of impressive.
Despite the fun theme, the party planning wasn’t very sweet.
It all started when the sistersdisagreed over what to serveat the party.
The Poosh founder even argued that serving unhealthy candy would go against her brand.
A frustrated Kim shot back, “Then why does your car have leather seats?
Why are you wearing plastic glasses?”
The argument didn’t end there.
“It’s Candy Land, not Gluten-Free Land,” she told Kourtney.
Eventually, family intervened and suggested a truce.
The sisters ultimately agreed to throw the party together with classic candy on the menu.
The party endedwith Kim admittingthat there was indeed way too much candy at the party.
Kris Jenner planned a family trip to Wyoming so the girls could bond and experience new things together.
Both Khloe and Kim revealed that they hoped to repair their relationship with Kourtney.
“I want to fix my relationship probably with Kourtney for those reasons,” Kim told the group.
She noted that the two of them bicker often and resort to being mean to each other.
“I mean yeah, I can be so mean,” Kim admitted to Kourtney.
Khloe chimed in with her perspective, saying thatbothKim and Kourtney are mean to each other.
The sisters, along with Khloe and Kendall Jenner, were discussing their careers.
Her exclusion of Kourtney’s name in that statement wasn’t very subtle.
“You act like I don’t do s**t,” Kourtney snapped.
“You have this narrative in your mind.
I will literally f**k you up if you mention it again.”
The eldest Kardashian kept true to her word and tossed a water bottle at Kim before shoving her.
The fight only escalated from there.
The two sisters began kicking, scratching, and slapping each other before being separated.
After noticing scratch marks on her arms, Kim again lunged at Kourtney as Khloe intervened.
Kourtney left the house in tears and later tooka break from filming.
They apparently apologized to each other behind the scenes.
The following season,Kris Jenner called Kourtneyin tears after seeing the footage.
Also crying, Kourtney expressed that she felt ganged up on by the family.
Back in 2016, Kourtney revealed that they’re frequently at odds when it comes to parenting.
“So even if it’s things with our kids, we’ll talk to each other about it.
“She said that she felt so degraded by you and you just started yelling at her.”
Kourtney denied yelling and explained she only confronted the nanny after her son asked her to.
Kim disagreed with Kourtney’s approach.
“Keep her, I don’t care,” Kourtney replied.
“She will not ever be around my kids.”
It all started when Kourtney said “I Do” to Travis Barker in May 2022.
During the couple’slavish wedding ceremonyin Italy, the bride and her sisters were dressed in vintage Dolce & Gabbana.
She later called Khloe in tears and accused her sister of lacking loyalty.
“I shouldn’t have to ask her for permission.
I thought I was being really mindful.
There were so many collections [I didn’t choose items from],” she explained.
So, Travis?“Yikes.
At a celebratory dinner, Kim even called her sister “such a hater” with Khloe agreeing.
At the dinner table along with the designers, they madea shady toastin honor of Kourtney.
