Amber Rose and Blac Chyna -- Reality Show Crashes and Burns

Amber Rose and Blac Chyna have pulled the plug on their reality show because they say they're both so busy doing other things they just don't have the time ... in other words, they hate each other now.

The two former best friends are telling their friends they have various projects that prevent them from joining forces on the boob tube. Amber says she's "in the process" of getting her own talk show, and Blac Chyna says she has various product deals.

That said, Amber held her Slut Walk in downtown L.A. last weekend and Blac Chyna was a no show, because she was hanging with Future in the ATL. It doesn't take a rocket scientist to figure out Amber was hot as fish grease.
