Wow! Either she's making a point to show Jake, Conor, Taylor, John and company what they're missing out on, or ... she's trying to wow One Direction hottie Harry Styles even more?

Taylor Swift worked the red carpet at the American Music Awards on Sunday night in a Zuhair Murad dress and Jimmy Choos, and she even gave us a sultry over the shoulder shot. Hot!

Taylor performed “I Knew You Were Trouble” during the show, which is reportedly about ex-boyfriend John Mayer. The 22-year-old singer is nominated for Favorite Country Female Artist, and she's up against Miranda Lambert and Carrie Underwood. Think she'll win?!
