Stop us if you've seen this one before...

Kylie Jenner peeled back her jeans to expose her massive naked ass on Instagram today, and if this shot looks familiar, it's because it's almost identical to one Kim posted a while back. We love how the 19-year-old's formula for success is just to copy everything her older sister does! The LipKit queen obviously got a Brazilian butt lift to get some Kardashian curves, so she's probably freaking out now that Kimmy K is downsizing hers.

We love how the mini mogul likes to pretend her booty is all natural!

“[I haven’t had] ass implants. You know, I used to be 120 [pounds]. I was really skinny. Now I’m pushing, like, 136. But it’s all right, I like the chunkiness. I don’t really think I have the fattest ass, but I know my angles,” she said in a video posted to her website earlier this year.

Did this whole family forget that their doctor's Instagram page is public?! He posts tons of videos of himself injecting people's bums with solution to make them bigger and rounder, and we sort of can't believe Kris Jenner didn't make him sign something to prevent the secret procedure from becoming public knowledge.

Just in case you were wondering, here's how the Keeping Up with the Kardashians stars get their butts...
