All the junk in Kim Kardashian's trunk is 100 percent real – and she has the photos to prove it.

The crack detective on the case? Kardashian's sister Khloé, who posted a photo on her blog, showing her sister posing with what appeared to be an X-ray. "Hey dolls. The PROOF is in the X-ray. Kim's ass is 100% real!!!" Khloé Tweeted.
