Anyone with sisters knows that fights and bickering are a common occurrence, especially growing up together and even more so during the angsty teenage phase. The same is true for famous families, and Kim Kardashian recently recalled the childhood feud with one of her sisters that left her feeling "so embarrassed."

On the February 27 episode of The Kardashians, the SKIMS founder shared a story about the time Kourtney Kardashian barged into her classroom at school after Kim borrowed a pair of her vintage Levi jeans without asking and demanded she return them immediately, per People.

"I was in sixth grade at a new school, I didn't know anyone and I wanted to look really cool and fit in. And I borrowed Kourtney's jeans that had these, like, cow patches on them," she said.

When the "pissed" Poosh founder realized what had happened, Kim said that Kourtney didn't let the fact she was attending different school at the time than her sister stop her from confronting her and forcing her to change.

"And then [Kourtney] comes in with the lamest shorts and makes me change into them," Kim recalled. "I was so embarrassed, and I have never gotten over what happened to me in sixth grade."

The revelation came as Kourtney and Kim posed together for a photoshoot for the Dolce & Gabbana collaboration with SKIMS, seemingly ending a feud sparked after Kim partnered with the fashion house after Kourtney's wedding to blink-182 drummer Travis Barker, after the brand sponsored the nuptials. Kourtney, who along with her sister is no stranger to airing out their grievances publicly, joked that Kim recruited her for the campaign to "get revenge on the jeans."

Kim also addressed speculation that arguments over clothing caused a real rift between the sisters rather than just a temporary disagreement.

"For anyone that thinks that we wouldn't even be cool because we got into a fashion fight over what we wear is crazy," she said. "That's what we were doing in elementary school."
