In a sneak peek of Sunday night's Keeping Up With the Kardashians episode, the 33-year-old reality star is seen calling out her younger sis for wanting to leave the vacation early.
"12:15 is looking real good," Khloé says at the table, and when asked what that meant she replies, "A flight that I have on hold to get the freak out of here. I'm waiting for my travel agent."
During a confessional interview, Kim tells the camera, "The fact that Khloé is trying to make all these changes to get out of here is really ridiculous. She's going to be traveling alone and pay a ton of money to change her ticket. And all for what? It just doesn't make sense."
Kim asks Khloé, "What's the point of coming all the way out here?"
"Kim, you can do whatever your heart desires, princess. I'm not ruining anything for you," Khloé says in a sarcastic tone. "Why don't you take some more selfies?"
North West's mama answers, "I'm doing it for Kanye [West]. Someone that I love."
"One day I'll be so lucky," Khloé says. "One day."
And as if you couldn't already cut the tension with a knife, Kim then goes, "Yeah, one day. You want to get home to your 50 rappers that you're dating. You're like a miserable person. You really are."
Khloé makes a shocked face and quips, "I'm a miserable person that takes wonderful selfies all day long."
