Kim Kardashian is sick of people saying that her bottom is scientifically enhanced...

Kim is denying reports that she has signed on to endorse a butt enhancement pill. In an interview with Rachael Ray, the curvaceous beauty says she would never promote a product she finds unnecessary.

Kim says, "I have said no to butt enhancement pills!...I’m like, I don’t think I need them & this is just crazy. I would never endorse a product like that!"

So, do you think her booty is all-natural?
