Swift adds another superstar collaboration to her expanding 1989 guest list.
Nico & Vinz join Taylor Swift on stage at her 1989 tour show in Vancouver.
It wouldn't be a 1989 show if there wasn't a Top 40 artist taking the stage with Swift, and Saturday's Vancouver show did not disappoint. Normally, Tay Tay sings the song with the featuring artist, but this time around she acted like one of the fans attending, dancing and bopping around on stage like a fellow fan during the duo's performance of "Am I Wrong." When Nico & Vinz ask everyone to put their hands in the air, Swift initiates the back and forth and the 60,000 fans in attendance followed.
