If you thought Taylor Swift's concerts in Los Angeles were star-studded, you haven't seen anything yet!
The 21-year-old just played two nights in Nashville and brought out all her friends for surprise duets. On Friday, Taylor tweeted, "Nashville, night one- what a beautiful crowd! And thank you to @yelyahwilliams and Ronnie Dunn for coming out and singing/being awesome."
She followed that up on Saturday with: "Thank you Nashville for an unforgettable night. Thank you Tim McGraw, Kenny Chesney, and Andy Grammer for joining me onstage!That was crazy!"
Man, we wish we could have been at those shows. Thank goodness for Youtube!
Which of these duets is your favorite?
