Kim Kardashian Tagged 'A Hater' For Birthday Post Of Sister Kourtney

It has been months since Kim Kardashian and her older sister, Kourtney Kardashian, ended their infamous feud; however, some fans believe there's still bad blood between them.

The drama went down on the oldest Karjenner sibling's 45th birthday when Kim uploaded a touching tribute alongside what many perceived as an unflattering picture of Kourtney.

On April 18, Kim uploaded a stunning picture of herself and her sisters, Kourtney and Khloe, posing in matching black bikinis. The snap was taken from a recent beach excursion, with the trio posing in front of the crystal clear waters.

If their happiness and sisterly bond didn't reach viewers, Kim doubled down on their affection for each other in the post's caption. She celebrated Kourtney's big day with a lengthy message, noting that she cherishes all their memories together.

"I will especially cherish this last sister trip where all of our kids had dance parties til they passed out, the way we all did growing up!" Kim penned, adding:

"Celebrating you today and grateful to you forever for always giving the best advice a sister could possibly give."

Unfortunately, the KKW Beauty founder's touching message didn't resonate with some of her followers. These fans called her out for being a "hater," alleging she chose to mark Kourtney's birthday with a bad picture.

The criticisms rained down on Kim in the comment section, with one fan writing: "Kim [picked] this pic. Clearly shows she's a hater." A fellow IG user agreed, adding: "Of course, she would post a picture where she looks good and outshines Kourt."

A third echoed similar sentiments with the comment: "Well, this was intentional," while a fourth speculated that there was still bad blood between the siblings. The individual's comment read:

"Tell me Kim and Kourtney are feuding without telling me Kim and Kourtney are feuding."

"Kim out of all the pics, c'mon," another displeased fan berated the cosmetics mogul. More IG users came to Kourtney's defense, with one slamming Kim and Khloè's figures by declaring:

"Seems like Kourtney is the only one with a REAL belly button."

A fellow supporter echoed: "Jokes on Kim cause I actually think Kourtney looks the best here… most natural."

The hate over the picture Kim shared stemmed from the fact that Kourtney didn't have the same toned figure as her sisters. One critic implied the mother of four wouldn't like the snap, writing:

"Now you know she's not going to like this photo... lol it's her bday Kim.. lol."

However, Kourtney shut down this speculation and all the other comments about her postpartum body. She declared that she has nothing to be ashamed of and loves every inch of her figure; in her words:

"I LOVE this photo! It is me and my sisters having the best time on a trip with our kids...and the memories to last forever! And I LOVE this body that gave me my 3 big babies and my little baby boy."

She also supported Kim in the comment section of her birthday post, writing: "I love you sooooo and so grateful for all of the incredible memories we have together… when I think it, it's like a movie plays in my head of all of them! So blessed!"

During the drama between Kim and Kourtney, The Blast reported that the oldest sibling's baby bump pictures had sparked wild theories about their relationship.

The incident occurred last October when Kourtney shared stunning images of her then-pregnancy.

The pictures were taken outdoors with the soon-to-be mother of four posing beside a pile of white pumpkins in a sheer floral dress. Although the snaps were promotional content for her fashion brand, it didn't stop fans from having wild theories.

"Watch her have the baby on her arch nemesis's birthday (October 21), lmaooo," someone claimed, referencing Kim's birthday. Another echoed similar thoughts, adding, "She gone have that baby on Kim's birthday watch."

A third noted the speculated due date would be an excellent punishment for Kim, writing, "That would literally make Kim so mad. Another person sharing attention on her birthday."

Last October, The Blast revealed the drama between Kim and Kourtney had reached a favorable resolution thanks to the oldest sibling. The news broke on an episode of "The Kardashians," where Kim shared the story with her glam squad, saying:

"Kourtney messaged me. She sent this picture of my dad in college. So Kourtney texts me, and I feel like it is a step in the right direction of moving past it and moving past all of the drama. I want her here."

As for Kourtney, she noted it was time to settle her differences with her younger sister, saying:

"I think we both said things that we are not proud of. But anyone who has sisters or siblings knows the dynamic. You could get into a crazy fight, and you can send a funny text, and everything is all good."
