Watch Billie Eilish bring out Charli XCX to perform ‘Guess’ remix in LA

Billie Eilish brought out Charli XCX to perform their ‘Guess’ remix at her show in Los Angeles last night (December 17). Watch the footage below.

The ‘Hit Me Hard And Soft’ singer performed the third of five scheduled dates at the Kia Forum in Inglewood, California yesterday as part of her current North American tour.

During the concert, Charli surprised the crowd by popping up from under a B-stage as the arena was illuminated in ‘Brat’-green lights and lasers. Eilish then headed up to the platform where the duo performed their collaborative reworking of ‘Guess’.

The song appears on Charli’s star-studded remix album ‘Brat And It’s Completely Different But Also Still Brat’, which was released in October.

Charli has since shared footage of the live team-up on social media, and wished Eilish a happy 22nd birthday for today (December 18). “love u billieeeeee and hbd!!! <3,” she wrote.

Charli and Eilish’s ‘Guess’ remix is nominated for Best Pop Duo/Group Performance at the Grammys 2025. The two artists are also competing for Album Of The Year, Record Of The Year, Best Pop Solo Performance and more.

Over the summer, Eilish celebrated Charli’s 32nd birthday at a very ‘Brat’ party in LA along with Lorde. The pair had previously donated 10,000 pairs of pants that were used in the video for their ‘Guess’ remix collab to charity.

In October, Eilish was asked whether she felt threatened by the recent successes of Charli, Chappell Roan and Sabrina Carpenter.

“Are you kidding me?” she responded. “I’m so happy for these bitches. It’s a crazy world when you get to the level they’re experiencing right now, and they’re doing great. Fans are drawn to them because they’re fucking awesome.”

Eilish will return to LA’s Kia Forum this Friday and Saturday (December 20, 21) with her final two gigs of 2024. Looking ahead, the star has recently teased that she’s been working on some “fun” new music.

Meanwhile, ‘Brat’ has been named as NME‘s album of the year while ‘Hit Me Hard And Soft’ landed at Number Nine on the list. Additionally, Eilish and Charli were both included in our 50 best songs of 2024 run-down.

In other news, Eilish was hit in the face by a necklace thrown onto the stage by a fan while she was performing in Arizona last week.
