Taylor Swift is coming clean about her latest pop hit 'I Knew You Were Trouble.' She told 'Time of London' magazine, the song was written about her last fling, One Direction's Harry Styles. The video is the latest to get mashed up.  Its no screaming goat, but its still funny.  Check out 'Trouble' with the Ron Burgundy payphone meltdown from Anchorman.
