Katy Perry stopped her Detroit concert to help a fan who collapsed after being brought onstage: 'It's overwhelming.'

Katy Perry, playing her first Little Caesars Arena show since 2017, delivered a fun pop spectacle — and kicked into mom mode when a young fan fell ill.

Katy Perry wants to be there for her fans. The "Teenage Dream" singer, 40, welcomed a few concertgoers on stage during her Lifetimes Tour stop at the Little Caesars Arena in Detroit on Sunday, Aug. 3, and after one of them collapsed on the ground in a startling moment, Perry stayed by her side to ensure she was safe.
