In case you somehow missed this drama, or need an update, the TL;DR version goes something like this:
— Kanye released a song called "Famous" containing the lyric "I feel like me and Taylor might still have sex / Why? / I made that bitch famous."
— He claimed to have called Taylor asking for permission to use the lyric and said she approved it.
— Taylor released a statement saying that she had warned Kanye of the song's "misogynistic message" and that he'd never asked permission to use the line "I made that bitch famous."
— Kim then released a video of parts of their phone call in which Taylor seemingly gave her permission for Kanye to use the "We might still have sex" lyric, but not the reference to her as "that bitch".
— Taylor then disappeared from public view for almost a year before returning with an album, Reputation, which appeared to address the feud in a couple of tracks.
