Earlier this week news leaked that Rob Kardashian and Blac Chyna were secretly broken up [click here if you missed that].
So the next logical step was quitting their reality show...
Rob is MIA for his own show. Chyna -- who's 8 months pregnant -- showed up for an appearance to promote "Rob & Chyna" and he was a no-show. He didn't even stop by the baby shower that was thrown specifically for him a few days ago.
One big problem ... Chyna is the one who pulled Rob out of his depression, but now the relationship has become the big problem -- they fight whenever they're together and it just deepens the problems.
