Who did country sweetheart Taylor Swift write "I Knew You Were Trouble" about?

Taylor Swift has a star-studded history with boyfriends, and while there are songs about Joe Jonas, Lucas Till, and, of course, John Mayer, this one was for Harry Styles. Months after their rumored fling, Taylor wrote "I Knew You Were Trouble" and later confirmed it was about the One Direction star.
