At the Los Angeles stop of her Ultrasound World Tour at the Kia Forum on Saturday night (October 18), Lorde closed her electrifying set by bringing out surprise guest Charli XCX to perform their confessional Brat remix of “Girl, So Confusing.” Lorde shimmied around on the b-stage while Charli delivered her potent verse, with the special guest eventually joining the headliner on the small stage as the two pop superstars shared an emotional moment together, joyfully dancing around as the song came to a triumphant close. The duo had previously performed their Brat collab together during Charli and Troye Sivan’s Sweat Tour stop at New York’s Madison Square Garden in September 2024, and paired up again during Charli’s Coachella set in April, but this was the first time that Lorde was the star of the show. The North American leg of the Ultrasound Tour concludes with two shows later this week in Portland and Seattle, before heading to Europe in November. (Billboard)
