Billie Eilish surprised fans with Charli XCX on Tuesday to deliver the live debut of their “Guess” (Remix) in Los Angeles at the Kia Forum. On the third of five nights at the arena for Eilish, the pair took the “Brat”-green lit stage to sing their Grammy-nominated high-energy track.
Charli posted footage of the performance on her social media and captioned the video, “love u billieeeeee and hbd!!! <3,” nodding to Eilish’s 23rd birthday. “Guess” (Remix) is a regular part of Eilish’s set, but this is the first time the singers performed the track together.
The remix appeared on “Brat and It’s the Same but There’s Three More Songs So It’s Not” and “Brat and It’s Completely Different but Also Still Brat.” Charli is also up for seven awards, including record of the year (“360”), album of the year and best pop duo/group performance for “Guess.” Eilish, meanwhile, is nominated for her “Hit Me Hard and Soft” album which is up for seven nominations, including album of the year and best pop vocal album.

Charli will embark on her own headlining “Brat” arena tour across the United States in the spring, following her “Sweat” tour with Troye Sivan. The pair hit New York City’s Madison Square Garden and the Kia Forum in a co-headlining 21-city trek that kicked off in September and concluded in late October. It marked both Charli and Sivan’s biggest venues to date.
Eilish will close the North American leg of her tour in Los Angeles on Saturday before taking a break until February. She will perform in through early March, followed by spring/summer 2025 dates across Europe.
