Taylor Swift, yet again, has some fresh material for a new breakup song: As rumored, Swift, 22, and One Direction's Harry Styles have split, multiple sources confirm to Us Weekly.
Things went south last week for the couple during a vacation on Virgin Gorda, the third-largest of the British Virgin Islands -- with Swift cutting the holiday short and jetting back home to Nashville.

"They had a fight," one insider tells Us. British crooner Styles, 18, "said something he shouldn't have . . . This [breakup] is definitely going to be for good."
"They are 100 percent over," another insider adds, noting that the "Red" chanteuse could be "intense."
