Rob Kardashian & Blac Chyna's Reality Show Fueled by Constant Conflict

Rob Kardashian and Blac Chyna squabble, scream and yell at each other, and that's the core of their upcoming reality show.

Production sources tell us fight topics range from Rob's diet to social media and lots in between, including money and fame.

Very little is not filmed ... we're told cameras are rolling for up to 13 hours a day, 5 days a week.

The tension has become increasingly exacerbated by Chyna's pregnancy.

We're told producers are chuckling at stories that Rob is now running hot and cold on doing a reality show. We're also told it's just caused more conflict between the 2, and the result is really good TV.
