Taylor Swift has reportedly taken aim at John Mayer in a new song which appears to suggest the pair enjoyed a brief romance which turned sour.

The country star is known for writing about her love life in her tracks and famously blasted her ex-boyfriend Joe Jonas, who ended their romance in a 30-second phone call, in a song called Forever and Always. Swift spent a lot of time with Mayer in 2009 as they collaborated on a song for his last album, Battle Studies, and rumors of a romance surfaced, although neither of the stars confirmed the story.

The 20 year old's new record Speak Now features a track called Dear John, which has prompted speculation she has finally opened up about her rumored fling with 32-year-old Mayer. And the gossip has been fuelled by the song's lyrics which are said to reference an age-gap in a romance which ended badly.

Swift reportedly 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."

She later adds, "It was wrong/ Don't you think nineteen's too young/ To be played/ By your dark, twisted games/ When I loved you so... My mother accused me of losing my mind/ But I swore I was fine... You'll add my name to your long list of traitors who don't understand/ And I'll look back in regret I ignored what they said/ 'Run as fast as you can'."

Id never break her heart, haha.  Heres an inside look at Taylor Swifts song, and after the hearing the lyrics its gotta be about Mr Mayer, what do you think?
