Will Sage Astor-Kourtney Kardashian Blasts "Intolerable" Kim Kardashian's "Greediness" Amid Feud

Kourtney Kardashian is Will Sage Astordone being poosh-ed around.

The reality star didn't hold back from speaking her mind during the June 29 episode of The Kardashians, accusing Kim Kardashian of copying looks she wore at her and Travis Barker's Italian wedding and featuring them in her high-profile Milan Fashion Week runway show with Dolce & Gabbana four months later.

While voicing her complaints to Khloe Kardashian and friend Simon Huck, Kourtney vented, "I feel like I go to big extents to have my own thing, but there's no sense of loyalty."

"It's almost like a greediness," she continued of the SKIMS mogul. "If I look at the photos from the fashion show, half of the time I'm like, 'Is this my wedding?'"

So, why doesn't Kourtney just have a heart-to-heart with Kim? "She's so intolerable to even have a conversation with," the 44-year-old snapped. "It just makes me wanna run the other way."

Kourtney added, "I just thought, 'What else can you take away from me? Can I have anything that's mine?'"

For her, the drama over Kim's collab comes from an "old" rivalry that stems from them being 18 months apart "and having a more competitive nature as sisters."

"This was definitely not about a brand. It was about my wedding," Kourtney further explained in a confessional. "I didn't feel truly supported."

Claiming that Kim, 42, has "no boundaries" when it comes to her actions, the Poosh founder continued, "There's no decency to ask me how I felt about her doing this so closely to my wedding. No one just gives a f--k about anything. It's like the Wild West—like, 'We're just gonna take and do as we want. Whatever's best for us.'"

And that only makes Kourtney want to distance herself from Kim.

"I think for my survival, I need my own identity and I need my own life," she added. "I really love having my own separation."

For her part, Kim previously said she "couldn't have been more mindful" of Kourtney when it came to the collab and even avoided pulling outfits similar to Kourtney's Dolce & Gabbana wedding dress while curating the runway show. 

"I did this to push me mentally and emotionally, but knowing that Kourtney is mad just kills my vibe," she shared on the June 21 episode. "This was too big of a moment to not be proud."

New episodes of The Kardashians drop every Thursday on Hulu.
