Everybody knows about Kim Kardashian butt implants plastic surgery. Several reputable plastic surgeons note that the large Kim buttocks are due to a different approach. A popular approach that Kim took was getting fact injection in the bum rather than getting silicone implants. Remember the x-ray done on Kim’s butt that was negative? This was due to the fact that fat injections cannot show up in an x-ray. However, the difference in Kim’s booty between 2006 and 2010 can clearly be seen in her before and after photos. Her waistline is the same but her butt is bigger.
