Katy Perry Performed ‘Witness’ Hits For 100,000 People At Glastonbury: Watch

Thousands flocked to the Glastonbury music festival over the weekend to witness Katy Perry's hit-filled performance.

The energy from the massive crowd even caught Katy off guard. "Sitting here, enjoying some fries in disbelief that I just played a show to about 100,000 people at @glastofest that voluntarily showed up to see me... (look mom I made it!)," she said. "I had so much fun and as you can see gave you all of me, literally. I can't wait to do it over and over again on Witness the tour... 👁❤️😩 Thanks to @glastofest for helping me feel like, cool or whatever."

The pop star, wearing a bedazzled, nude-tone bodysuit with an eye on the front of it (because obviously), powered through the classics – “Teenage Dream,” “Firework,” “Dark Horse,” “ET,” an acoustic rendition of “Thinking Of You,” “California Gurls,” "Roar" and “I Kiss A Girl.” She also used the opportunity to perform her new single, "Save As Draft," a fuzzy love ballad, as well as her Nicki Minaj-assisted single "Swish Swish" and the record's lead single "Chained to the Rhythm."
