A source close to the situation explained:
Who knew Aaron Tveit was a Swiftie?!
The Les Miserables star performed a cabaret show at 54 Below in New York City Friday night, and while the set list was full of Broadway hits, Aaron made sure to include one special track for his fans. Yep, you guessed it. None other than Taylor Swift’s We Are Never Ever Getting Back Together!
On putting his own show together, the singer said that "it's wonderful because you just get to sing what you want to sing."
Loves it! Keep up the good work, Aaron!
