On Sunday's all-new episode of Keeping Up with the Kardashians, it will be on between Kim Kardashian and Khloe Kardashian.
Seriously on. Hard.
In Thailand, the sisters will clash over Khloe's desire to go home, with Kim taking a slam at how Khloe is dating like "50 rappers," (even though it's really just one, French Montana) and Khloe bashing Kim for taking so many selfies.
The exchange gets rather personal, concluding with Kim referring to Khloe as "miserable."
It looks like E! writers worked extra hard to make this fight catty and intense. Watch now!
