Swift will debut the official clip for “I Knew You Were Trouble” on MTV as the capstone to a weeklong birthday celebration, The Hollywood Reporter has learned.

"As soon as I started writing this song, I knew it was different from anything else on the record, so I knew that I wanted the video to be different from anything we'd ever done," says Swift of the darker-than-usual subject matter. "I wanted to tell the story of a girl who falls into a world that's too fast for her, and suffers the consequences."
