American Music Awards 2012: Best and worst moments

Taylor Swift switched things up for a performance of her dubstep-inspired "I Knew You Were Trouble" (we're pretty sure it was written about John Mayer). When she ripped off her sparkly dress to reveal a red room of pain corset and angry-'90s-teen combat boots, though, she just made us sort of uncomfortable. She can go back to singing about crying at marching band practice any time now.
