During her performance of 'Roar' at the Chase Center, Katy Perry was startled when a butterfly prop suddenly jerked and dropped, causing her to momentarily stop singing and regain her balance.

She shared a photo of her terrified expression from the incident on her Instagram Story, captioned 'Goodnight San Fran,' and audience members captured the moment on social media.

Despite the scare, Perry managed to continue her performance, and she humorously remarked, 'Not today, Satan,' as the prop safely returned to the ground.

This incident is part of a broader trend of stage mishaps involving aerial props, with other artists like Beyoncé experiencing similar malfunctions, such as a flying car tilting mid-air during her 'Cowboy Carter' tour.

Perry's reputation for bold, theatrical performances includes previous incidents, like a stage intrusion in Sydney last month and a toppled steel ball during her current tour, which she handled with poise.

The mishap has raised safety concerns among fans and critics, prompting calls for stricter safety checks on elaborate stage setups.

Social media reactions ranged from jokes to worries, with some fans questioning the safety of such risky props in performances.

Reactions to the incident reflected a mix of admiration for Perry's professionalism and concern for her safety, especially as she continues her North America tour known for its extravagant stage elements.

This is not Perry's first encounter with stage disruptions; she previously dealt with a stage invasion in Australia and a near fall when a suspended sphere toppled.

Representatives for Perry have been contacted by CNN for comments regarding the incident, but no official statement has been issued yet.

The incident occurs amidst Perry's personal challenges, including her recent breakup with Orlando Bloom, although she remains committed to co-parenting their daughter.

The incident echoes a similar malfunction during Beyoncé's tour, highlighting the risks associated with aerial stage elements for pop artists.
