Katy Perry reacts as fan storms concert stage: ‘What the hell?’

A fan really didn’t want to go-oh after storming the stage during a recent Katy Perry concert.

When Perry was performing her hit song “Hot N Cold” at the Qudos Bank Arena in Sydney, Australia, on Monday night, a fan rushed onto the stage to dance next to her. The singer appeared visibly shocked in a fan video posted to social media as the man put his arm around her and began jumping up and down.

After freezing for a second, Perry spun around to create distance from the man as she kept singing the lyrics to “Hot N Cold.” The stage crasher then began to perform the floss dance move before security rushed onstage to escort him off.

As the man resisted, Perry said into the microphone, “Well, there’s never going to be another show like it, so just enjoy it, Sydney.” She sang a few more lyrics before shouting into the mic, “What the hell is going on?!”

This is just the latest concert mishap for the singer throughout her tour, after she nearly suffered a major wardrobe malfunction while performing at the Las Vegas stop when the clasp on her bejeweled brassiere appeared to break.

“Oh s‑‑‑, my bra’s gonna come off,” Perry said to the crowd. Eventually, she called to an assistant in the wings named Patrick to “put my bra back on.”

Last month, Perry abruptly stopped performing midsong at her Houston stop to call out the haters on social media who had been making fun of the way she over-enunciated her words in her 2008 ballad “Thinking of You.” As fans in the crowd sang the song’s lyrics at her during a break, Perry looked directly at them captured in videos posted to TikTok. “I’m not going to do it,” she said.

But then she launched directly into the second verse of “Thinking of You,” which recently went viral on TikTok as users filmed themselves lip-synching, “You’re like an Indian summer in the middle of winter, like a hard candy with a surprise center,” while making exaggerated, hilarious facial expressions. During the concert, Perry sang those exact lines, complete with exaggerated facial expressions of her own. But she cut it off after the words “candy with a” to declare to the crowd, “I don’t sing like that.”
