Kesha delivered a cutting-edge performance at Lollapalooza … quite literally.

After hitting the stage at the music festival in Chicago on Thursday, the pop star, 37, revealed the prop blade she used during her performance was actually swapped for a real butcher knife by the stage crew without her knowledge.

“Sooooo apparently the prop knife went missing and they replaced it with a real butcher knife stolen from the kitchen,” Kesha claimed in a post on X, formerly Twitter, just hours after her Aug. 1 performance. “I didn’t know. Till now. So watch that again.”

The “Die Young” crooner, who was seen running around the stage with the knife in hand while performing her tune “Backstabber,” did not reveal who allegedly switched out the prop blade.

Kesha managed to dodge a catastrophic disaster considering her set featured a moment when she paraded the sharp blade around stage while pretending to stab her dancers.

HuffPost has reached out to representatives for Kesha and Lollapalooza for comment.

Social media users on X were flabbergasted over the wildly dangerous mix-up.

The horrified reactions over Kesha’s post spilled over to Reddit in a pop culture forum.

“How do they opt for a REAL knife instead of having a back up prop knife??,” one person questioned. “Thank God nothing happened since the knife was the focal point of the song and part of the choreography was ‘stabbing at’ her backup dancers for the song, Backstabber.”

Another user compared the mishap to the tragic “Rust” shooting, in which actor Alec Baldwin discharged a prop gun that killed Halyna Hutchins, the director of photography on the set of the Western film. “Have we not learned anything from the Rust case?,” they wrote.

Someone else added, “After the Alec Baldwin shit? Really???? I would fire every single one of them on the spot.”

There hasn’t been any word on the whereabouts of the missing prop as of yet.

Kesha was joined at the weekend festival by dozens of other artists, including Megan Thee Stallion, SZA, The Killers and Blink-182.
