Here it is in bullet-point form, in case you need catching up:
– Kanye West wrote a song, "Famous", in which he said he and Taylor "might still have sex" because he "made that bitch famous".
– Kanye claimed Taylor knew about the song and gave him her approval.
– Taylor claimed that she never gave Kanye her blessing, and called the song "misogynistic".
– Kim Kardashian called Taylor a liar in an interview with GQ, and said that Kanye had video proof of Taylor giving her approval.
– Kim released said video on Snapchat for all the world to see, and shit hit the proverbial fan.
