After a bitter on-camera feud with her sister, Kourtney Kardashian Barker is airing out just who is behind the group chat apparently made for the sole purpose of complaining about Kourtney, the eldest Kardashian sibling.

The group text was revealed during the season 4 premiere of “The Kardashians,” where sister Kim Kardashian claimed during an argument that all of Kardashian Barker’s friends were complaining to the family in a chat labeled “Not Kourtney.”

On Friday, Barker posted another set of photos from her Disney-themed baby shower with her husband, Blink-182 drummer Travis Barker, on Instagram. The pictures included photos of the pregnant 44-year-old reality star posing with Mickey ears on a lawn with a group of friends.

One commenter on Instagram asked the eldest Kardashian sibling if those friends happened to be in the “not Kourtney groupchat” to which she replied: “no the members of that chat are namely Kim, Khloe, Kendall and Kylie. Case closed.”

A clip of the phone call between the sisters went viral on X, with users divided on whether or not Kardashian took the conversation too far. In the clip, she also mentions that the “Poosh” CEO’s three kids have come to the “Skims” founder to complain about their mother.

The fight stemmed from a disagreement about Kardashian working with Dolce & Gabbana, the same designer that helped put together the Barker’s wedding.

Some said that Kardashian was being unusually cruel to her sister, while others think that the digs were deserved.

“If you actually watch their show & see their dynamic, you’re on Kim’s side. If you don’t watch their show and only see these clips, you’re likely on Kourtney’s side,” one user said.

Reps for Kardashian did not immediately respond to Insider’s request for comment.
