Taylor Swift and Kanye West's feud is the biggest celebrity fight of the century; they went from falling out to making up to become sworn enemies.
And now the singer, 29, has shed some light about what happened behind the scenes, explaining she only approved the lyric in Famous to stay on Kanye's good side.
In 2015 she presented him with the Vanguard Award at the MTV VMAs after he'd begged her to do it, but she wasn't prepared for what happened next.
As she spoke about all his achievements Kanye shouted out that she was only there to give the awards show good raitings.
Taylor told Rolling Stone : "I'm standing in the audience with my arm around his wife, and this chill ran through my body. I realized he is so two-faced.
"That he wants to be nice to me behind the scenes, but then he wants to look cool, get up in front of everyone and talk s**t."
She stopped talking to Kanye until he sent her a bunch of flowers to apologise and when he rang she answered the phone.
It was then that he asked her about the lyrics to famous, which claim they could still sleep together and that he is responsible for her success.
She laughed at them but then later claimed she'd never approved of the word "b***h", and then Kanye's wife Kim Kardashian leaked a video of the phone call.
Taylor still maintains that she never approved of the use of that word.
She continued: "And then when I heard the song, I was like, 'I'm done with this. If you want to be on bad terms, let's be on bad terms, but just be real about it.'"
In an interview with Vogue last month Taylor hit back at trolls who told her to kill herself over the feud .
She described the whole “mass public shaming” experience as “isolating”.
