London: Taylor Swift has penned a brand new song called ‘Back To December’ in a bid to apologise to an ex-boyfriend whom she treated "carelessly".
Admitting that she often writes about her love life, the country star added that her latest song has sparked speculation as to who the subject of her latest lyrical rendition was.
"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... This is a song full of words I would say to him," the Daily Star quoted Swift as telling E! Online.
On the track, Swift sings, "You gave me all your love and all I gave you was goodbye. So this is me swallowing my pride. Standing in front of you saying I’m sorry for that night."
