Kourtney Kardashian never misses an opportunity to tease her little sister Kim.

Despite their notorious relationship, the sisters are currently vacationing in Turks and Caicos with Khloe.

That’s when Kourtney decided to mock Kim for an incident that happened nearly two decades ago but, thanks to the meme, has likely stuck with her ever since.

On Sunday, Kourtney posted a photo of herself swimming in the ocean on her Instagram, including one that showed her covering her ears with her hands to inspect her earrings.

She hilariously wrote: “My diamond earring fell off in the ocean and disappeared.”

Of course, this is a reference to Kim’s infamous meltdown in Season 7 after she lost her diamond earring while swimming in the ocean. Keeping up with the Kardashians Aired in 2007.

“Kourtney, people are dying,” Kardashian-Jenner matriarch Kris retorted in the comments, referring to Kourtney’s initial response to Kim.

The SKIMS founder finally addressed the incident last year, saying the joke was “out of date.”

“Whenever I’m in the water, people ask me if I found my diamond earrings in the ocean,” she said in an interview QIt was further revealed that her half-sister Kylie Jenner actually ended up finding the earrings.
