Last month there were rumors that Rob Kardashian was having second thoughts about filming a reality show with fiancé Blac Chyna [click here and here if you missed that].
Looks like the rumors were true...
Insiders tell TMZ
Rob has been skipping filming over the last month, complaining that the show is compromising their relationship.
Rob also believes 'KUWTK' has destroyed his family, and fears the same will happen with his relationship with Blac Chyna if they put everything out there for the new show.
As a result he's been a no-show for various shoots ... notably a big Kardashian shindig in San Diego celebrating his grandmother's birthday. Blac Chyna ended up filming solo.
