Watch Taylor Swift bring out Rachel Platten to perform “Fight Song” on the second day of Philadelphia concert of The 1989 World Tour. The crowd goes absolutely crazy.

Absolutely stunning performance by the two ladies.

Before taking up the stage last night, a few days before Taylor Swift released some short clips on Instagram of Blink 182 performing “Fight Song” in a backstage room at The 1989 Tour. Little did we know, that little session would turn out to be a mega performance at the grandest stage of all.

Yup, that’s Taylor Swift flashing her bellybutton by herself, backstage at the Philadelphia concert.

Pretty eventful night for Taylor, I would say.
