Rob Kardashian, Blac Chyna constantly argue on camera?

Celebrity couple Rob Kardashian and Blac Chyna's reality show is reportedly driven by their constant arguments.

Insiders claim the couple, who are expecting their first child together, are always arguing during filming of their new reality show "Rob & Chyna", reported TMZ.

Production sources said they fight over a variety of issues, from the reclusive sock designer's weight, to posts on social media, to money and fame, and very few things are not filmed.

The tension between them has only been exacerbated by Chyna's pregnancy. The pair is being filmed five days a week, for up to 13 hours a day.
