Lorde performs at Lollapalooza in Chicago with Charli XCX joining her onstage for a surprise reunion

CHICAGO, IL — Lorde made a memorable comeback to Lollapalooza on Thursday night, and the Chicago crowd got an extra treat when Charli XCX appeared during the headlining set. The moment turned an already major festival slot into one of the weekend’s buzziest pop reunions.

For Lorde, the performance carried added weight. Her 2017 Lollapalooza appearance was cut short because of weather, so returning to Grant Park for a full-scale headline set gave fans a long-awaited redo.

A long-awaited return to Grant Park

The New Zealand singer used the stage to move through hits and show how her sound has developed over time. The set underscored how much her live presence has grown since her earlier festival run, which ended before it could fully build momentum.

Charli XCX’s surprise arrival lifted the energy even further. The pairing gave the night a crossover appeal that resonated with fans who follow both artists closely, especially after Charli’s own headline set at the festival on Friday.

Charli XCX added another layer to Lollapalooza weekend

Charli XCX arrived at the festival as a headliner with a set that reflected her mix of hyperpop edge and mainstream reach. Reports from the festival noted songs from her latest album, Music, Fashion, Film, which has been welcomed warmly by listeners and critics.

Her onstage reunion with Lorde gave the night a conversation-starting twist, but it also fit neatly into a festival lineup designed to keep big names moving across multiple stages and genres.

Rain chances did little to slow the festival buzz

Lollapalooza 2026 runs from July 30 through August 2 and features more than 170 artists spread across eight stages. Other major names on the bill include The Smashing Pumpkins, Tate McRae and Olivia Dean.

Even with forecasts calling for showers across the weekend, the Chicago festival remains a centerpiece of summer music season. Beyond the performances, it continues to draw huge crowds and deliver a meaningful economic boost for the city.
