Taylor Swift gave a fantastic performance of her new song ‘I Knew You Were Trouble’ (rumored to be about ex-boyfriend John Mayer) last night, Sunday, November 18, at the 2012 American Music Awards.
Swift showed up on stage in a pretty white gown and later in the song stripped it off to reveal a red/black tulle outfit.
