Katy Perry​ powered through a midair prop malfunction during her concert in San Francisco, California, on Friday night.

A scary moment occurred late in Katy Perry’s sold-out concert at Chase Center in San Francisco on Friday. It happened during one of the Perry’s (roughly) 278,433 aerial/high-rise sequences in the show, as the superstar boarded a giant black mechanical butterfly and soared off high above the crowd during the anthem “Roar.”
