It looks like Taylor Swift might be done with her "We're Never Getting Back Together" phase. Because instead of performing her smash first single off her Red album, Taylor showed up to the American Music Awards performing the dubstep-influenced "I Knew You Were Trouble."
For Taylor's performance, the singer went for some kind of twisted, haunted-ballroom theme. All of her background dancers were wearing suits and masks, while in the middle of her performance, Taylor changed from an all-white dress to a sexy red and black number.
