Kim Kardashian is tired of the peeps who are saying her rear is nothing but an implant.

To prove her junk in the trunk is the real deal, the sexy reality star took a photo next to an X-ray of her booty. Her sister, Khloe, posted the pic on her website.

So is the X-ray convincing enough? No butts about it. See a photo of Kim's rear ... after the jump.
