Besides being the two youngest members of the "Keeping up with the Kardashians" clan and the two only daughters of Kris and Caitlyn Jenner, Kylie and Kendall have always seemed to be their own bond due to their close ages and having grown up with much older siblings - but is their camaraderie over?

As Kendall becomes one of the highest-paid models in the world and Kylie follows the steps of superstar big sister Kim Kardashian to become the next fashionista in the family, it appears like Kylie and Kendall Jenner no longer share the close union they always have, and it's now affecting future TV plans for the family.

According to Life and Style Magazine, as the two young stars' popularity rises, there were plans to give the two the Khloe and Kourtney treatment and release a spinoff about Kylie and Kendall Jenner's adventures outside "Keeping up with the Kardashians," but the project may have been scraped due to their constant fighting.

"Kendall is just not having it anymore," a source close to Kylie and Kendall Jenner told Radar Online recently about the plans for their own spinoff. "She does not want to be a part of this spin-off because Kylie is trying to make it all about her. More and more, she thinks that Kylie's complete intent with this is to turn it into the 'Kylie show guest-starring Kendall.'"

In Touch Weekly reports that, besides this, Kendall isn't all that convinced that their vastly different lifestyles would match in a single reality show, as she hangs out with some of the biggest supermodels in the world (including Hailey Baldwin, Cara Delevingne and BFF Gigi Hadid), who all refer to Kylie's crew as "ratchet fame whores."

It seems like while Kendall struts the biggest catwalks in the world such as the Victoria's Secret fashion show, Kylie has turned into a big diva, forcing a strain into Kylie and Kendall Jenner's traditionally very close relationship.

Could Kylie and Kendall Jenner ultimately get their own reality show outside the Kardashians?
