Swift told MTV News the song was an apology for a former boyfriend who she treated badly. And it just so happens her and the Twilight cutie busted up... way back in December.
"'Back to December' is a song that addresses a first from me in that I've never apologised to someone in song before," Swift admitted while talking about the song.
"Whether it be good or bad or an apology, the person I wrote this song about deserves this. This is about a person who was incredible to me, just perfect to me in a relationship, and I was really careless with him. So, this is a song full of words that I would say to him that he deserves to hear."
Swift's attempt at an apology may not land her the boy but it will undoubtedly find her at the top of the charts... again.
