The relationship between the Kardashian and Jenner clan appeared to be crumbling down.

Recently, a source reported to RadarOnline that Kendall Jenner and Kylie Jenner faced some disputes with Khloe Kardashian. The Jenner sisters then eventually admitted that they were already sick of Khloe's constant drama.

The sais insider revealed that Kylie and Kendall warned the recent "People's Choice Awardee" that they will cut ties with her if Khloe's self-obsession continues to get worse.

The said self-obsession roots from the constant problematic attitude of Khloe. According to the testimony, the "Keeping Up with The Kardashians" star never called back and never cared about anyone else. During meetings, Khloe would either arrive late or cancel the conference at the last minute.

She also had numerous attempts in badmouthing Caitlyn and the other members of the infamous family, which ignited the issue more.

"They're sick and tired of Khloe's drama and want nothing to do with her unless she gets her act together," the source said.

The Kylie Cosmetics owner also reportedly highlighted the stressful, endless drama of her half-sister's love life and her absence during Caitlyn Jenner's 70th birthday celebration.

Amid Tristan Thompson's multiple cheating scandals on Khloe, Kendall and Kylie stayed beside her. They also tried to console her when she got deeply hurt after Thompson cheated with Kylie's best friend, Jordyn Woods. The never-ending issues and change of mind of Khloe, however, frustrated the sisters even more.

Meanwhile, during the birthday bash of Caitlyn, Khloe went missing in action. To recall, she got mad at her former stepfather for slamming their momager, Kris Jenner, in her 2017 tell-all book titled "The Secrets of My Life."

The absence became somehow still acceptable, but Khloe posted enigmatic messages on Instagram instead of birthday greetings. Their fans hinted that the posts were about Caitlyn, and it was not okay with both Kylie and Kendall.

The source also confirmed in the same report that the two did not buy the excuse of Khloe, despite sending Caitlyn a bouquet for her birthday.

Fans did not know anymore if Khloe is still suffering from all the issues she had this year, or if she has some sort of attitude problem.

Recently, she won the "Best Reality Star" award at the People's Choice Award where she was bashed because she snubbed the award and her fansShe claimed that she did not even know that she won since it was too loud inside the venue.

Whether her reasons are true or not, it is now up to the listeners to buy them or not.
