No more Ms. Nice Girl: Taylor Swift is taking the haters to task on a trio of new songs and is singling out one person in particular.
The 20-year-old "Love Story" singer has reportedly written a song slamming her former duet partner and alleged beau, John Mayer, 33.
The duo was rumored to be dating back in 2009, around the time they collaborated on Mayer's song "Half of My Heart."
In her new song, "Dear John," Swift apparently takes the crooner to task for ruining their May-December relationship.
"Dear John/I see it all now that you're gone/Don't you think I was too young/To be messed with," she sings. "It was wrong/Don't you think nineteen's too young/To be played/By your dark, twisted games/When I loved you so."
Swift does not name names but recently told Yahoo that her songs aren't usually too vague and that fans should be able to read between the lines to figure out who she's singing to.
