What Is Wrong With Blac Chyna's Photo?

All the work done on Blac Chyna's butt seems to be taking its toll. The mother-of-two was spotted out following her online row with baby daddy Rob Kardashian, but what's striking about the photo taken of her is her backside.

It's still curvy but a part of it looks kind of deformed. Rob disclosed that he paid  $100K for her to get work done on her body after their daughter was born but from the look of things she might need more body work.
