If you, like us, replayed Taylor Swift’s “Look What You Made Me Do” music video over and over to catch all the subtle and not-so-subtle jabs, you’re probably shamelessly curious about peeking into the pop star’s attempt at that plot-twisting Taylor Mountain. In a clip shared exclusively by People, we got to see behind-the-scenes footage of the record-breaking anthem as well as the artist going face-to-face with the extras who played her former selves. (2009 VMAs Taylor and geeky “You Belong with Me” Taylor, FTW.) “This is the trippiest thing I’ve ever seen in my life,” she announced upon walking onto the set. “Seeing all of them together is the weirdest feeling, but it’s awesome.” Well, of course it’s weird, Tay—there are literally 14 versions of you epically battling one another on a makeshift pyramid. Here, the real T. Swift shows off the costumes she dug up from her archives and the decisions behind one of the most viral music videos in history.
