Kesha Unknowingly Used Real Knife During Lollapalooza Performance

The singer discovered post-show that a prop knife was swapped for a real butcher knife during her set.

Kesha performed with the real knife during her song 'Backstabber' without realizing it.
The knife switch occurred before her performance, and she was unaware until after the show.
Kesha took to social media to inform fans about the incident and urged them to rewatch the footage.
Her Lollapalooza set included hits from her career and her new single 'Joyride'.
This performance marked one of her first major shows since leaving Dr. Luke's label.
