Kesha‘s performance at Lollapalooza in which she danced with a knife was even scarier than it appeared.

Turns out, the knife was real.

‘Sooooo apparently the prop knife went missing and they replaced it with a real butcher knife stolen from the kitchen,’ the 37-year-old claimed on X after her Thursday performance of her 2010 hit track, Backstabber, in Chicago.

‘I didn’t know. Till now,’ she told her fans, adding, ‘So watch that again.’

In addition to Backstabber, Kesha’s Lollapalooza set included her new single Joyride.

She showcased her versatility, playing guitar live during her performance of Your Love Is My Drug.

She also performed the viral version of her classic hit Blow, using the laugh from Vice President Kamala Harris’ coconut tree speech, asking ‘You think you just fell out of a coconut tree,’ which fans had grabbed to for a remix on social media.

After the show, the Joyride singer posted a sweet video clip with her band members writing, ‘Grateful for my boys,’ and tagging Nick Annis, Elias Mallin and digital creator Logan Schynynck.

In another snap Kesha wrote she was ‘grateful for my besties,’ tagging pals Shelby Scudder and Diana Suarez.

The performance was one of her first since leaving Dr. Luke’s Kemosabe label following her years long legal battle with the music producer.

In 2014, Kesha accused Luke, born Łukasz Sebastian Gottwald, of assaulting her in 2005 after she allegedly woke up in his bed ‘sore and sick with no memory of how she got there.’

In the suit, she claimed record executive threatened to ‘shut her career down’ if she told anyone of the alleged incident.

Luke countersued for defamation and continued the case even after Kesha dropped her lawsuit in 2016.

It was finally settled out of court in June 2023, one month before it was scheduled to go to trial.

She left Kemosabe Records in December 2023.

Lollapalooza was scheduled to continue over the weekend at Chicago’s Grant Park.

The Killers, Future X and Metro Boomin were set to headline Saturday. Blink 182, Melanie Martinez and Skrillex were on the bill to lead Sunday’s shows.
