Proving that she hardly ever sleeps, Taylor Swift showed up on the Los Angeles set of her new music video for “I Knew You Were Trouble” last night (November 18).
The “Enchanted” songstress looked punky pretty with dip-dyed hair and a black leather jacket as she filmed scenes with a hunky hat-wearing costar.
According to insiders, Taylor wrote “I Knew You Were Trouble” about her ex-boyfriend John Mayer whom she dated awhile back.
Prior to the video shoot, Miss Swift was busy rocking the house at the Nokia Theatre as part of the 2012 American Music Awards.
