Swift Admits "I Knew You Were Trouble" About Styles

Taylor Swift and Harry Styles initially dated in the summer of 2012, and that is what she penned the now hit song "I Knew You Were Trouble". Swift was sitting for an interview with UK's The Sunday Times and the 23-year-old made it shockingly obvious that the song was written about her former One Direction flame. Swift was speaking about her heartfelt performance of "I Knew You Were Trouble" at the Brit Awards - if you remember she was wearing a wedding dress, as Styles watched from the audience.  Swift told the times of the performance "Well, it’s not hard to access that emotion when the person the song is directed at is standing by the side of the stage watching. “You’re balancing the analytical side of your brain, which is telling you where to go and how to go there, with the other side of your brain, which is saying ‘Feel everything you’re singing, and show it on your face. Feel everything exactly as you felt it when you wrote the song."

Presently, Swift's scenes in the upcoming One Direction movie 1D3D will be left on the cutting room floor.
