Kim Kardashian & Blac Chyna POSING & POSTING BOOTY & BREAST Shots

The "Kanye Workout Plan" seems to be working for new besties Kim Kardashian and Blac Chyna.  See their revealing selfies inside....

You know you've made it into Kim Kardashian's intimate circle when she starts including you in her selfies. On Instagram, Kim shared a "bootylicious" pic of her and Blac Chyna, posing in the bathroom, with her 12 million followers.  We're not hating....but one (or maybe both) of those rear ends might be fake.  We're just saying.....

The ex-sex tape star and retired-from-the-pole stripper also shared a gratuitous "chest" shot. Again...one (or maybe both) might be fake.  In addition to working out, shopping and dining together, it seems as though Kim and Blac Chyna has established a genuine friendship.  We wonder if Ms. Tyga has asked Kim for advice on promoting her new clothing label?
