Taylor Swift lets the audience sing along during her live performance at the 2014 Z100 Jingle Ball at Madison Square Garden on Friday afternoon (December 12) in New York City.
“This is my last tweet as a 24-year-old. #casual,” the now 25-year-old singer tweeted before hitting the stage.
Earlier that night, Taylor showed off some skin as she arrived on the red carpet for the big event.
