Katy Perry dealt with a scary incident on her “Lifetimes Tour” over the weekend. The “Woman’s World” singer, 40, had several young fans in the audience join her on stage for a rendition of her 2011 song “The One That Got Away” at the Little Caesars Arena in Detroit, Michigan on Sunday.

Katy Perry is currently in the midst of her Lifetimes Tour in North America, and she paused a show in Detroit on Sunday, Aug. 3 to help a fan who collapsed on stage.

Later in the show, Perry asked concertgoers to join her in a brief prayer after the young fan was removed on a stretcher.
