Kim Kardashian West isn't afraid to speak her mind -- even to her sisters!
In a sneak peek clip from Sunday's all-new episode of Keeping Up With the Kardashians, the 36-year-old reality star has a heated moment with Khloe Kardashian during their family vacation to Costa Rica.

The clip begins with mom Kris Jenner walking over to Khloe in hopes of turning her frown upside down.
"So, I was just talking to Kim and she was telling me that you weren't feeling like this trip was going the way that you would have wanted it to go," Kris says. "And we're not spending enough time, all of us together."
Khloe replies, explaining that "It's just interesting" how she doesn't get to see her family a lot.
"I take the time to come here thinking, like, 'Oh, great, this is time where I get to be with my sisters and my nieces and nephews and do all these things, and this house is absolutely extraordinary, but going to the beach and, like, just doing -- when will I ever go to a Costa Rican beach? I don't know," Khloe says. "Kylie [Jenner] and Tyga are locked away in their room. You and Corey [Gamble] are doing whatever you and Corey do. You don't like to do any activities. Kim has her things where she's…whatever."

Kim chimes in, saying, "Just because I was afraid of the whitewater rafting? Like, what's the point of making it not fun for us to want to hang out with you if you're always snappy?"
"So no one hang out with me!" Khloe responds. "Get away from me! Everyone can get away. You've ruined my mood already today, so you guys can all get away from me!"
When Kourtney Kardashian tries to come to a solution that would make everyone happen, Khloe just doesn't seem to be having it.

"I'm over all you people now," she says out of anger and frustration. "Ungrateful family members that I can't."
That's when Kim adds her two cents!
"See, this is what I can't handle," she explains. "You're so annoying. It's like, shut the f**k up! You're the negative one, just saying how awful we are. You're like a big bully that bullies all of us!"
