Kesha says she 'didn't know' prop knife was replaced by 'real butcher knife' during Lollapalooza performance

Kesha's always been known to go all out for her fans. This time, however, she apparently didn't know what she was getting herself into. 

During her set at Lollapalooza 2024 on Thursday, the 37-year-old singer dominated the stage with performances of some of her biggest hits. During her rendition of "Backstabber," Kesha – who was rocking a blood-stained tank top and mini skirt – took her theatrics to the next level while running around with a knife and consistently making stabbing motions.
