If Charli XCX is the queen of chaos this Brat summer, Chappell Roan just crowned herself the court jester.

In one of the most unexpected, and utterly iconic, moments of Primavera Sound’s opening night, pop provocateur Chappell Roan surprised fans by performing the viral “Apple” dance during Charli XCX’s set on Thursday, June 5. The scene unfolded at Barcelona’s Parc del Fòrum, where thousands gathered to kick off the beloved music festival, and got far more than they bargained for.

A Rottenly Perfect Pop-In

Charli, mid-way through her 31-song adrenaline rush of a set, was performing the now-infamous “Apple” track from her Brat album when the jumbotron zeroed in on a group of fans in the crowd. Among them? None other than Chappell Roan herself , unmistakable in bug-eyed sunglasses, a cropped sweatshirt, and the kind of energy only someone born for theater could bring.

Without missing a beat, Roan began lip-synching along to “I think the apple’s rotten right to the core…” while perfectly executing the dance’s signature hand jive. The moment was silly, chaotic, and expertly timed, everything you’d expect from two of pop’s most genre-defiant forces.

Charli, catching sight of the performance, screamed into the mic: “Make some f–king noise right now! Chappell, I f–king love you, b–ch!” And honestly? Same.

The Brat Tradition Lives On

Charli’s Brat-era shows have taken on a delightful tradition: a live crowd cam moment where fans (and, increasingly, famous faces) perform the “Apple” choreo originated by TikToker Kelley Heyer. Roan joins an eclectic and star-studded lineup of past “Apple” dancers — including BLACKPINK’s Rosé, Clairo, Dave Grohl and his daughter Harper, Stephen Colbert, Ashley Tisdale, and Glen Powell, to name just a few.

But something about Roan’s chaotic joy and sheer commitment to the bit made the moment instantly iconic.

Fan Reactions Were Feral

It didn’t take long for social media to melt down. Clips of the moment flooded TikTok and X (formerly Twitter) within minutes.

“Me telling my gay roommates chappell roan was the apple girl tonight,” one fan posted.

Another wrote, “Chappell Roan was tonight’s apple dance! Y’all I cried my eyes out!!!”

Many fans even joked that Roan should just permanently take over the role, with one saying, “No offense but no one else needs to do the Apple dance again. It’s been perfected.”

What’s Next for Roan at Primavera?

This was just a warm-up for Chappell Roan, who’s set to headline her own Primavera Sound set on Saturday, June 7. With her theatrical flair, campy visuals, and newly-minted Apple dance credentials, expectations couldn’t be higher.

Before Chappell performs on Saturday, queer favorites like Haim, Beach House, Wet Leg, and Sabrina Carpenter will be performing on Friday night, but if Roan’s surprise appearance was any indication, she might just steal the weekend.
