Ever since she waltzed into the limelight, we've all questioned the authenticity of Kim's assets. So after being egged on by sisters Khloe and Kourtney, she decided to prove her naysayers wrong by doing what any reality TV star would do in this situation: getting a butt X-ray and documenting it on her reality show Keeping Up With the Kardashians. After Kim's check-up with the family doctor, sister Khloe took to her Twitter account and shared the image with the entire Twitterverse saying, “Kim got a butt X-ray…See, it’s REAL!!! LOL.” Some of us still have our reservations, but the X-ray speaks for itself.
