Taylor Swift turned 30 years old on Friday (Dec. 13), and she's spending her big day performing at Z100's Jingle Ball at Madison Square Garden.
Not a bad way to celebrate, but her fellow performers made it even more special by wishing her a happy birthday through an epic montage video played before her set. "Welcome to the Dirty 30s club, Ms. Swift!" Katy Perry shouts to open the sequence.
"You know how much I love you," Camila Cabello adds. "I hope you have the best, most cat-filled, most Lover-filled, most incredible birthday."
