The TL;DR version: Kanye West released a song called “Famous,” which included a lyric about having sex with Taylor Swift. He claimed she’d approved the lyric, she denied it. She then referred to the incident in her Grammys acceptance speech which led to Kim Kardashian claiming she had proof in the form of an audio recording where Taylor appeared to approve the lyrics. Taylor denied it again. So Kim leaked the audio on Snapchat, Taylor’s reputation imploded, and she disappeared for months.
