Last night, Taylor Swift brought her Speak Now tour -- and some very special guests -- to New York City's Madison Square Garden. And joining her on stage on the last night of her tour was BFF Selena Gomez. Right before Selena came out, Taylor told the crowd that this performance was even more special since it would be the first time that Taylor and Selena had ever sang together. Selena was just as excited about the duet, Tweeting, "Performing at Madison Square Garden with my best friend was a highlight.. Congratulations Taylor on Speak Now tour!! Love you"
