So much Kardashian news so few hours in the day................ Rob Kardashian has officially shut down all rumors that he and girlfriend Blac Chyna are on the outs, with a detailed explanation posted Sunday on his instagram page of course! The caption read- ?We just feel like it would be a lot healthier for our relationship if we kept a lot more to ourselves. It?s impossible to have a positive relationship with so much negativity from the media and outsiders and we would appreciate it if everyone respects that.?
