Katy Perry paused her concert in Detroit after a fan she had welcomed onstage suddenly collapsed. In video footage, Perry can be seen greeting a group of young fans and giving them shakers to perform with her. However, one fan named McKenna appeared overwhelmed, prompting Perry to guide her through breathing exercises. As McKenna collapsed, the audience gasped, and Perry remained by her side, holding her head up until event staff arrived to assist. Perry later said a brief prayer for McKenna, empathizing with the feeling of stage fright, and informed the crowd that the girl was doing well before continuing the show. This incident comes less than three weeks after Perry experienced her own scare when a butterfly prop she was riding suddenly plummeted several feet during her San Francisco concert. Despite the malfunction, Perry held onto the insect and continued singing. (EW)
