Katy Perry stopped her 'Lifetimes Tour' concert in Detroit to help a young fan, McKenna, who collapsed on stage during 'The One That Got Away'

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 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.
