Sources tell TMZ ... KK used to love her Ghost Rolls ride (which runs a cool $250k base price) back when she was with estranged husband Kris Humphries.
But people move on ... and we're told she started singing a different tune when she got with Kanye West ... and chose to go back to black ... as in paint color ... for the car -- and traded it in.
You know what they say -- once you go black ... you never really leave.
