Holy Butts! Kim Kardashian & Blac Chyna Flaunt Their Abs & Derrieres

Kim Kardashian and her gal pal Blac Chyna  are showing off their butts and abs in a pair of new selfles.

"Getting right for the new year," Kardashian tweeted along with the pics of the girls in their workout gear.

Kim's toned abs and chiseled waist have some of her followers crying "photoshop" but even if she got a little high tech help with her look, she still has brought her body back a long way since giving birth to little Nori  last summer.
