Perry, rocking a white blazer over a revealing black top and white pants, performed the high-energy synth-pop song in front of a seemingly idyllic house with a white picket fence -- which also served as a backdrop for increasing fiery projections.
As the semi-psychedelic performance continued, she was joined by collaborator Skip Marley -- grandson of the legendary Bob Marley -- and as the pair began to conclude the performance, Perry and Marley made a striking political statement.
As the tune came to a close, Perry and Skip stood together, hand-in-hand, in front of the preamble to the Constitution, which was projected in massive scale on the wall behind them, with the words "We The People" spelled out above their heads.
It was one of the night's few political statements, but it was a memorable one. Perry, 32, also made a statement with a "PERSIST" arm band -- referring to the recent censoring of Elizabeth Warren on the floor of the U.S. Senate -- and a Planned Parenthood pin on her lapel.
ET spoke with Perry on the GRAMMYs red carpet, where she opened up about the fun experiment, sharing, "I love making people go outside, and I love the interaction. I love launching something in a different way. I've always done that kind of thing." Check out the video below to hear more.
