Rob Kardashian and Blac Chyna little fights, scream and yell at each other have become the core of their upcoming reality show.


Production sources tell TMZ the 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. Producers are chuckling at stories that Rob is now running hot and cold on doing a reality show, and it has caused more conflict between the 2, and the result is really good TV.
