All the junk in Kim Kardashian
's trunk is 100 percent real – and the reality star 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.
The, ahem, butt of the joke retweeted the post. The things my sisters have me do! Proof baby!" Kim Tweeted
Kardashian isn't the first star to turn to modern science to debunk rumors. In 2005, Tyra Banks
had an on-air sonogram
to prove that her breasts were real.
