During her headlining show at Madison Square Garden in New York tonight (September 23), Charli XCX brought out Lorde to perform “The Girl, So Confusing Version With Lorde.” It marked the song’s live debut with both artists singing together in person. Charli XCX and Troye Sivan, who are currently on their joint North American arena tour, also invited Addison Rae onstage to perform her single “Diet Pepsi” together, as well as her “Von Dutch” remix. Watch those moments happen below.

Though the Lorde collaboration was initially released as a standalone remix of the Brat single “Girl, So Confusing,” Charli XCX recently revealed that it’s included on the upcoming record Brat and It’s Completely Different but Also Still Brat. Due out October 11, that remix album also features the previously released tracks “360 Featuring Robyn and Yung Lean,” “Von Dutch A. G. Cook Remix Featuring Addison Rae,” “Talk Talk Featuring Troye Sivan,” and “Guess Featuring Billie Eilish.”
