FANS have spotted Kourtney Kardashian throwing a major diss at her famous sister Kim Kardashian.
In her latest post, Kourtney, 44, seemed to prefer another skincare brand over Kim’s SKKN line.
The Kardashians star took to an Instagram Story and uploaded a snapsH๏τ of the Mario Badescu products stockpiled together.
THE COMMENTS
In an online thread, fans claimed the Lemme founder was throwing shade by promoting “someone else’s skincare products.”
One fan noted: “This looks like a nice promo to me! Kim sure wishes it was for SKNN.”
Another fan added: “The packaging is trying to make it look like it’s a nice small company. It looks so homemade.
“Kourt probably thinks Kim cannot do that with SKNN.”
A third fan mentioned: “Kourtney’s life is not Kim’s business opportunity.”
A fourth person wrote: “If Kim paid Kourt like she does with her sponsors, maybe she would have chosen SKKN for sure.”
Another commentator chimed in: “I love seeing the snark between Kourt and Kim.”
VITAMIN C
Kourtney’s post came after her sister used her skincare products in her most recent video.
During the makeup tutorial, Kim pushed up her boobs with her sports bra while explaining why her product does not turn brown like other vitamin C serums.
The beauty mogul said: “One of the reasons why I really wanted to have a thin, liquidy vitamin C serum was because everything has to blend well under makeup. 
“And I wanted all my products to be able to layer really well.”
THE FEUD
Last month, Hulu shared footage of the siblings feuding in the upcoming third season of their family show.
In April 2022, Kourtney and her husband, Travis Barker, 47, held their Italy wedding in Portofino.
In the footage, the mom of three angrily accused Kim, 42, of using her wedding as a “business opportunity.”
Kim asked sibling Kendall Jenner, 27: “She’s mad at me?”
In a confessional, Khloe Kardashian, 38, claimed Kourtney was “livid.”
While speaking to her other sister Kylie Jenner, 25, Kendall added: “She felt like her wedding vibes were, like, stripped from her.”
Kim defended herself: “I’m really confused about how this narrative came into her head.
“I couldn’t have been more mindful.”
The TV star continued explaining: “I said: ‘Don’t do anything that Kourtney wore to her wedding.'”
Kourtney’s sister referred to her collaboration with Dolce & Gabbana. who famously sponsored the couple’s wedding. 
Months later, Kim worked with the Italian fashion house to create her own collection.
After hearing her explanation, Kendall reluctantly admitted: “I see both sides,” as Kylie agreed.
Kourtney blasted Kim and said: “People think it’s a misunderstanding. It’s not.
“It’s who she is to her core.”
