Taylor Swift, 22 Singer, Possible Subject of John Mayer Song Paper Doll [VIDEO]; One of Her Many Exes; Plus Taylor Swift Perfume Launch!

Taylor Swift 22 singer has a new perfume, Taylor by Taylor Swift.  It premiered just in time for the fourth of July. 

Its ad campaign showed the 22 singer playing with sparklers.  The video also shows Taylor Swift swinging, posing for photos, sitting fully clothed in a bathtub, and generally having a great time in an off-the-shoulder blue peasant dress.  The ad's soundtrack is Taylor Swift's song "Starlight," from her album "Red."

According to E!Online, Taylor by Taylor Swift is the singer's third fragrance.  Previous Taylor Swift Perfumes were Wonderstruck and Wonderstruck Enchanted. The new Taylor Swift scent features a combination of peonies, hydrangeas and vanilla orchids paired with fruity notes from lychee and tangerine, making for a sweet, light fragrance, just like her sweet, light music.

Taylor Swift has been in the middle of a songwriting controversy lately.  She supposedly wrote the song Dear John about ex John Mayer, singing the lyrics: "You paint me a blue sky/ And go back and turn it to rain/ And I lived in your chess game/ But you changed the rules everyday/ Wonderin' which version of you I might get on the phone, tonight/ Well I stopped pickin' up and this song is to let you know why"

John Mayer said that writing songs about exes is "cheap songwriting".  The Wonderland singer said: ""It's abusing your talent to rub your hands together and go, 'Wait til he gets a load of this!' That's bulls--t . . . It really humiliated me at a time when I'd already been dressed down."

However, John Mayer may have broken his own code with his new song, Paper Doll.  The song explicitly references the number "22", which is a track of Taylor Swift.  The lyrics to John Mayer's Paper Doll include: ""You're like 22 girls in one/ And none of them know what they're running from/ Was it just too far to fall for a little paper doll?"
