In the middle of Katy Perry's eccentric and stunt-filled concert in Detroit on Sunday, everything stopped when a young fan collapsed onstage.⁠ ⁠ Perry had brought up the young guest, along with three others, for a live performance of “The One That Got Away." It's a part of her set she has done at several other stops on her Lifetimes Tour.⁠ ⁠ But just after she announced the song, the young girl collapsed and the crowd fell quiet.⁠ ⁠ Tap the 🔗 in our bio for the full story⁠ ⁠ #katyperry #concert #detroit #michigan #lifetimestour
