Justin Timberlake, Alanis Morissette, The Weeknd, Fifth Harmony, The Band Perry and Fetty Wap are just a few of the artists that have joined her, making this tour's surprises some of the most musically diverse and exciting yet. Friday night, Taylor Swift brought out Aerosmith's Steven Tyler to perform "I Don't Wanna Miss A Thing."

But nothing could have prepared us for who Taylor chose to bring out during her sold out show at the Bridgestone Arena in Nashville, Tennessee Saturday night.

Mick Jagger

YES, THE ONE AND ONLY MICK JAGGER! The Rolling Stone joined Taylor for an energetic performance of "(I Can't Get No) Satisfaction," and we can barely contain our excitement. Check out videos from the epic duet below.
