Taylor Swift and Selena Gomez duet together for the first time ever.

Hey everyone this is Nora Gasparian for Hollyscoop. Taylor Swift and Selena Gomez might be bff's but they have never really hit the stage together...that's until now.

Fans got a huge treat during Taylor's concert at NYC's Madison Square Garden on Tuesday night when Selena hit the stage for their first duet ever.

It was a sold out show and the last stop on her worldwide 'Speak Now' tour.

Obviously the crown went wild when they saw Taylor's bestie hit the stage. The to sang a pop rendition of Selena's song 'Who Says?
That wasn't the only surprise at Taylor's show. Later on in the night, Rock and Roll hall of famer, James Taylor hit the stage for a first ever duet of his classic 'Fire and Rain.'
It was actually really cute, because Taylor revealed to the crowd that she was actually named after the legendary singer..
