Taylor Swift & Rascal Flatts Duet Hurts The Most (In A Good Way)! Watch It HERE!

Gurl has done it again!

As if Taylor Swift hasn’t brought out enough special guests during her concerts for her RED Tour, she topped herself once more!

Swifty had Rascal Flatts pop onto stage with her in Nashville to perform What Hurts the Most!

And the duet is just as AH-Mazing as expected!

What’s super sweet about their appearance is she once toured and opened for them before she was a big, mega, huge superstar!

Ch-ch-check out the incredible duet…AFTER THE JUMP!!
