The Kardashian sisters seems to be jealous of Kylie Jenner's continuing success as they could not keep up with her anymore.
Kylie recently recently teamed up with Coty, seeling them a 51 percent on her Kylie Cosmetics company for $600 million. The tie-up is in line with the mission of the beauty mogul to turn the company into an internationally-acclaimed beauty powerhouse for her fans.
To celebrate, her mom Kris Jenner mentioned her in an interview with CNBC's "Squawk Box" and proudly considered it as a "crystallization" of all their works.
"Yesterday was a really big day for Kylie and our team at Kylie Cosmetics. [It was] truly a moment for our family to be proud," Kris stated.
Opposite from what Kris said, however, Kylie's half-sisters put down their wine glasses and declined to have a toast with her to congratulate her.
Far from the usual response of Kardashians-Jenners, the sisters Kim, Khloe and Kourtney failed to personally celebrate with Kylie. Certainly, the three showed a lack of interest over the news, or maybe they are boiling on the inside because of it?
Scrolling through their Instagram pages, they deserted the Kylie Cosmetic's owner by posting multiple KKW promotions instead.
The youngest sister among the clan, Khloe, shared a photo from KKW photoshoot alongside the caption "The OG Trio" -- which also expressed that the three are the only "Keeping Up With The Kardashians" original stars.
The omission made by Khloe completely surprised her fans since she was one of the closest to Kylie among the KUWTK's stars.
Meanwhile, Kim got too busy advertising her businesses the whole day. She posted photos of her products and kept on plugging them. She also manifested the fact that she completely ignored both Kylie Cosmetics and its owner after she reserved a time to congratulate Malika Haqq and her sister on their new show.
In just 24 hours, Kim filled her Instagram page with posts about her make-up artist, Kanye West, and her daughter Chicago's photograph.
Kourtney, meanwhile, also posted a picture of the trio and remained the quietest about their half-sister.
Even before Kylie expanded her businesses, both Kim and Khloe already displayed resentment towards the 22-year old billionaire.
A source told ladyfirst that ever since Kylie Cosmetics towered beyond their matriarch's expectations, Khloe felt neglected because of the existing competition between the Kardashians and Jenners for their mother's approval and attention.
"Khloe wants to be a mogul too and she's doing great with Good American, but the numbers don't lie," another insider revealed to HollywoodLife, referring to now the billion-worth Kylie Cosmetics. The source added that Kris only celebrates Kylie's success and that made the youngest a little envious.
On Kim's part, she promoted her brother Rob Kardashian's clothing line, Halfway Dead, amid the surrounding scandals during that time. The almost-dead company was brought back to life after Kim posted Rob's brand on Instagram and Twitter.
Most fans thought she only did it to prove that she is still better and more influential than Kylie, who received the title "Youngest Self-Made Billionaire" from Forbes.
Despite the controversies the family members are making, they are still siblings in the end.
