Taylor Swift supposedly writes song about John Mayer

Taylor Swift’s "Innocent" is about Kanye West, her newly released "Back to December" might be about Taylor Lautner and "Mean" is all about her critics.

 But it appears that the country sweetheart is singing about another guy, John Mayer.

 There is no confirmation that the track titled "Dear John" is about Mayer, but some of the lyrics that have surfaced make us wonder if it is him she is singing about.

 In the sing, Swift calls out someone for a love gone terribly wrong. She sings, "Dear John/ I see it all now that you're gone/ Don't you think I was too young/ To be messed with/ The girl in the dress/ Cried the whole way home/ I should've known."

  Taylor collaborated with the 30-something Mayer on a tune titled "Half of My Heart," which appeared on his 2009 album, Battle Studies, and the two had been rumored to have dated for a short period after they worked on the track.
