This is the very definition of "Rich People Problems."
In a sneak peek video from this Sunday's "Kourtney & Khloe Take the Hamptons," Kim Kardashian and her mom Kris Jenner get into it over which one of them gets to buy a swanky NYC apartment.
After touring a number of pads in NYC, Kris apparently tried to talk Kim out of making an offer somewhere ... only so Jenner could try and make a grab for it behind her daughter's back.
They both start calling each other "super shady" for sneaking around over real estate, before Kim storms off in a huff.
Just watch the ridiculousness go down above.
Last night, Kim and Kris joined forces to support Rihanna at her first ever Diamond Ball -- the two showing up in matching all-black ensembles. Check out more pics from the event below.
Elsewhere in the Sunday night's episode, Khloe Kardashian rides a horse ... and her booty is absolutely mesmerizing.
