Taylor Swift made a surprise appearance at The Rolling Stones' United Center concert in Chicago on Monday night. The country-gone-pop singer joined the rock legends on stage to perform the band's beloved ballad, “As Tears Go By.”

From the start, Mick Jagger admitted that they hadn’t played the song live in a long time and would need some special assistance. On cue, Swift sauntered onto the stage and was greeted by applause of approval. Swift’s addition certainly captured everyone’s attention, captivating an already mesmerized audience as she was twirled around the stage near Jagger.
