I Knew You Were Trouble was an idea that I got almost 6 months before I got scheduled to write with Max Martin and I emailed him and said “i just got this idea I can’t wait to bring it to you, I know we’re not ready for a few months but I just i need you to know I thought about this thing I can’t wait for you to hear it” and I’ve never written a song like that where it’s like it’s not shame on you, you broke my heart but it’s shame on me you broke my heart. I saw the red flags from the first second. —Taylor Swift
