Kendall Jenner Said Kylie Has 'Serious Issues' After A Very Physical Fight

While in the car, the sisters began their argument when Kendall expressed her wishes to return to her apartment.

"Kendall! Shut up!" Kylie screamed at her sister, per Buzzfeed, while they rode home from Palm Springs, saying, "No one promised to take you home! Why would I drive you over the hill?!"

The girls were very clearly hitting each other and yelling in the vehicle, with Kris Jenner's boyfriend, Corey Gamble, attempted to intervene and get the two to stop fighting. Visibly annoyed with the situation, Kim Kardashian called her security detail to get Kendall.

As a reply, Kendall yelled back at her sister that her reasoning for striking her was justified because Kylie had hit her first.

"You put your heel into my f****** neck!" Kendall said, to which Kylie replied with, "That's because you f****** slapped me!"

With a clear history of getting physical with one another since they were kids, a clear answer could only be achieved once the two were separated, and Kendall shared her opinion after she joined Kim in a separate car.

"I will never speak to Kylie ever again," Kendall explained to Kim, Khloé, Kourtney and Kris when they split from the original grouping with Kylie in the car, heading off in their own truck to avoid furthering the issue. "She smacked me, so I came back at her and smacked her in the face, and then she took her heel and put it to my neck. So I started kicking her back."

However, when the aftermath was addressed in the subsequent episode, where Kylie dissected the issue further.

"I think that she thinks she's right in the situation and I think I'm right in the situation," Kylie explained adding that she was in "happy, party mode" and didn't have a problem with finding Kendall a ride, citing a "miscommunication" and maintaining that the issue corresponded with the night overall being "blown out of control."

"I love my sister," the Kylie Cosmetics founder added, "I think we'll figure it out just like we always do. It was just an unfortunate situation."

On Kendall's side at the time, she was reluctant to speak to her sister, saying, "There's been multiple times in the past couple days that I've thought about calling her and just being the bigger person, but I kind of want her to grow up and realize that what happened was wrong, and that I do deserve that phone call."
