Kim Kardashian has been looking pretty thin and trim lately but you guys don't have to worry, she's still got the one asset that made her famous. That butt!

She showed off her rump at a nail salon in Beverly Hills, CA in a pair of black tights instead of the high-waisted jeans she been wearing recently. I think no matter what Kim does to try and shave off a few inches, her rear end is thankfully here to stay!
