Taylor pulled a Miley! Well, no. Not even remotely close, but it was one of the singer's raciest clothes ever. While we're already used to Taylor letting the world know that she's done with the whole princess-y image - wearing plenty of leggy outfits - it was the first time that the country singer actually rip off her clothes on stage. This was during her performance at the Grammy Nominations concert aired live Friday night on CBS. She changed her Victorian-styled gown into a sexy black romper while performing her hit song, "I Knew You Were Trouble." Way to go T-Swift!
