There's an epic sibling war that's been brewing on Keeping Up With the Kardashians, leaving viewers to wonder whether Kim and Khloé are wrong for ganging up on Kourtney. The sisters have been going to loggerheads with Kourtney since season 17 when she threatened to leave their long-running reality show.

Kourtney's departure from the inner sanctum of the sisterhood could be blamed on her lifestyle choices. In previous seasons of Keeping Up With the Kardashians, Khloe was lighthearted and easygoing. However, in recent years - particularly since becoming a mother - Kim's parenting style is geared toward being a working mom who has it all. Khloe also demonstrates a different relationship to parenting ever since giving birth to True.

The drama heated up again in season 18 when Kourtney returned to the show, but still displayed a lack of interest in adhering to the KUWTK shooting schedule. This caused the rift between the sisters to reignite. In the latest episode, Kourtney finally confronted Khloe, saying, "It's not that you're siding with Kim, it's that you're siding with production when this, honestly, has nothing to do with you." Khloe retorted, "Then, don't talk about it in front of me." Later, in a taped confessional, Kourtney lamented"For years, it used to be Khloe and I against Kim. And for the last, maybe, three years, it's just been such a different dynamic where it's Kim and Khloe against me."

After trading barbs and dirty looks as only these sisters can, the episode culminated in one last row. Kourtney, Khloe, Kendall, and Kim were together when the topic of baby sister Kylie came up. Apparently, she had to bow out of a fashion show appearance due to illness. Kim explained that she would've walked the runway even if she were on her death bed. Kourtney took this comment as a personal affront to her work ethic and quickly ripped into Kim. The KKW mogul delivered her famous Mona Lisa smile to her older sister during her tirade, prompting Kourtney to retaliate by dousing her with water. This led to Kim threatening to physically fight her sister. Khloe tried to diffuse the tension, but it was too late. Things quickly deteriorated, and their tension ultimately turned violent.

It's not the end of the world that Kim and Let the haters hate ... especially the ones in the family!
