But when it comes to business, it's a little different.
Kim Kardashian has just released a brand new eyeshadow palette as part of KKW Beauty, however one look at it and we're all like, 'That's Kylie's Royal Peach Palette."
Obviously, fans have picked up on the blatant copy & paste.
It's not the first time Kim's done the dirty on Kylie either, dropping a line of concealers right after Kylie did only recently.
We think momager Kris Jenner will have to step in on this one.
