During Sunday's episode, viewers were shocked to hear Khloe Kardashian tell sister Kourtney Kardashian that she wanted to "slap" her in her "f*cking mouth."

During the episode, Khloe was tense about an upcoming trip to Bali without her daughter'

"My biggest anxiety of this whole Bali trip is the travel," Khloe told the cameras. "I really don't know what to expect. Am I just gonna need to be in a padded cell after this? I have no idea."

Khloe was at odds with her sisters during a recent trip to Japan, and claimed that they were all being "really critical and judgy."

Kourtney, who ia a career complainer, later began to moan about an assistant's packing skills (which were not up to par) before taking a shot at Khloe.

"You're telling me that I'm f*cking critical because I asked not just to be lied to about my daughter? If you get lied to about the f*cking weather you throw a f*cking fit. God forbid it was about your child," Khloe responded.
