Now, if you're not familiar Blac Chyna and Kim Kardashian use to be really good friends. I guess the friendship kind of went sour when Kim's sister Kylie Jenner started dating Blac Chyna's baby father Tyga. To top all of that off Blac Chyna then became new besties with Amber Rose who is Kim Kardashian's husband ex girlfriend who he's constantly beefing with for whatever reason. First, Amber Rose & Kim Kardashian posted a selfie together and now not even a week later Kim Kardashian is posting selfies with Blac Chyna who is now dating Rob Kardashian. Hollywood Is Messy!
