In an interview with Rolling Stone magazine, Perry said that this song and "I'm Still Breathing" were about the same ex-boyfriend. She added "Ur So Gay" and "Mannequin" were about different exes.
This acoustic ode was produced by Butch Walker ("Fall For You", "When You're Gone").
Perry told Inthenews.co.uk that this song gets the best response at her live shows and it even reduces some fans to tears. She explained: "People do get emotional when they hear that song, because I think a lot of people go through that stuff so it hits them where they remember it happening to them. And it's just me with my guitar, rather than all the pyro and the dancers and the glitter, and I enjoy taking advantage of that, but sometimes it's nice to be able to take all that away and just do what I was put here to do."
