But Kourtney, 44, and Kim, 43, have seemingly reconciled enough to joke about past arguments.

The Poosh founder – who turns 45 on April 18th – celebrated her birthday a little early this year.

The reality star shared snaps from over the weekend where she indulged in several different cakes to ring in the big milestone.

In a new Instagram post shared on her feed, Kourtney posed while on a lavish yacht in the ocean.

She looked tanned and cheerful, wearing a black fishnet bathing suit coverup with pearl details.

The mother of four had her dark hair slicked back into a bun and she wore light glam makeup.

In front of Kourtney sat a massive white birthday cake with orange icing.

In the center of the dessert, there was a cake topper reading, “Happy Birthday to the most exciting to look at.”

MAJOR MELTDOWN

The message was a hilarious ode to an iconic fight between the Lemme founder and her sister Kim from a 2018 episode of Keeping Up With the Kardashians.

In the viral moment, the sisters argued about the timing of a photoshoot, with Kourtney setting strict boundaries to leave the dressing room at 4 pm.

But her younger sibling was not having it, and the two had it out in an intense on-screen altercation.

After yelling various obscenities at the eldest Kar-Jenner, Kim closed the conversation by telling her mom Kris, 68, and sister Khloe, 39, that Kourtney is the “least exciting to look at.”

BIRTHDAY GIRL

In addition to the initial photo in her new post, the birthday girl also included a second shot of her in full laughter next to the cake.

She flaunted diamond earrings on her left ear, holding her sunglasses in her hand as she prepared to cut the cake.

Kourtney also added photos of all of her birthday desserts from over the weekend and some throwback shots of her from birthday celebrations of her childhood.

She included a video of her blowing out the candle on a unicorn-colored cake from what appeared to be a throwback celebration.

The TV star captioned the post, “mood,” with a red balloon emoji.

FAN COMMENTS

Fans were hysterical over Kourtney’s hilarious cake topper, with many taking to the comments to praise her for the jab toward Kim.

“Happy birthday to the most interesting to look at,” one gushed, bashing the Skims founder’s claim.

“Well deserved cake. You really are the most exciting to look at!” a second agreed.

“Happy birthday kourtney you always been my favorite Kardashian,” a third complimented.

“Ppl are dying Kim,” a fourth wrote, mimicking Kris’s response to her daughters’ KUWTK meltdown.

“The cake with ‘the most exciting to look at’ has me screaming,” a fifth laughed with several crying emojis.

“That cake topper,” a final wrote with laughing emojis.

SISTER SISTER

Kim and Kourtney have had a difficult relationship over the years.

Their disagreements reached a breaking point when the Poosh founder said “I do” to Travis Barker in May 2022.

But the sisters have seemingly mended their feud for the time being, as they recently vacationed together for spring break in Turks and Caicos.

The Hulu stars whisked their children away for a luxury trip to the Caribbean.
