"Say it to them. Or say it to yourself in the mirror. Say it in a letter you'll never send or in a book millions might read someday. I think you deserve to look back on your life without a chorus of resounding voices saying 'I could've, but it's too late now."
'We Are Never Ever Getting Back Together' was a song that I wrote with Max Martin and Shellback and it happened really spontaneously, while we were writing this guy walked into the studio, he was friends with my ex and he made some comment about how we were probably gonna get back together, he left, I went on a rant that sounded something like: ”You know, the thing is, we are never ever getting back together. Like, ever. I'm never going through that again. That was… like, ever. We are never getting back together”. And Max looked at me and said: ”We have to write that” and we did, and as soon as I played it for anyone in my life that I trusted, they just kept singing it over and over again, and got it stuck in their heads and I'm really happy when I look out into a crowd of thousands of people singing the words back to me knowing that it came from such a spontaneous and fun thing.
