When Khloé decides to stay behind to look after pregnant sister Kourtney instead of going to Paris Fashion Week, Kim claims she needs to “get out and live her life”

Kim Kardashian appears to be over Khloé Kardashian’s behaviors lately.

In PEOPLE’s exclusive sneak peek of the season 5 premiere of The Kardashians, dropping on Hulu on May 23, the SKIMS mogul jets off to Paris Fashion Week with her mother Kris Jenner, and her mom’s boyfriend Corey Gamble.

As the trio figure out sleeping arrangements on the private plane, Kim, 43, gets frustrated when she’s reminded why Khloé, 39, decided to opt out of joining them on their overseas trip.

“Khloé is unbearable these days,” Kim tells the cameras. “Khloé’s not coming and honestly, she’s just not feeling it. When you’re not feeling it, there’s nothing that can force you to come and have a good time, like you will just be miserable.”

She adds, “I’m not in the mood to deal.”

In a confessional of her own, Khloé reacts to Kim’s comments with wide eyes as she offers a rebuttal to her older sister’s claims. Though she may have other reasons for choosing to stay home, Khloé points out that their sister Kourtney Kardashian Barker is in the late term of her pregnancy and will give 𝐛𝐢𝐫𝐭𝐡 any day now.

“Kourtney is at the very end of her pregnancy. I feel like someone has to be here,” she admits. “Even for all the kids, like God forbid there’s a natural disaster. I just felt somebody has to be here.”

The Good American founder acknowledges that she’s an “overthinker” while explaining her rationale behind staying back, adding, “I know I’m insane, welcome to my mind.”

Kim, on the other hand, believes that her desire to be home is rooted in something deeper.

“She needs to get out and live her life,” she says in a confessional. “All arrows are pointing towards misery. She feels guilty for leaving and she just should be home.”

In a trailer for season 5 that was released earlier this month, fans saw new tensions arise between Kim and Khloé. When Kim insinuated her sister has “a stick up” her a–, Khloé defended herself by pointing out, “You are going through a lot right now and you’re taking it out on me.”

After Kim demanded she “get out”, Khloé told the cameras, “I don’t care what other people think. I’m happy!”

Season 5 of The Kardashians premieres Thursday, May 23 at midnight. ET on Hulu.
