Charli XCX recently celebrated her 32nd birthday, and she had some of her ‘Brat’ co-conspirators by her side at a party.

Last Saturday (August 2), Charli XCX hosted her birthday party at a private event in Los Angeles – commemorating both turning 32 and the ensuing success of her latest album.

At the star-studded shindig, which boasted attendees like Rosalia, Anya Taylor-Joy and Glen Powell, Charli was joined by Lorde and Billie Eilish as they played their collaborative tracks over house speakers.

Footage shared by fans on social media show Lorde singing along to her confessional verse on ‘Girl, so confusing’ alongside Charli, with the crowd joining in on the line “Let’s work it out on the remix”. Later on, Eilish joins Charli for their ‘Guess’ remix, which was released last Friday (August 2).

Fans also commemorated the first new pictures of Lorde and Charli together since 2014, when both were in attendance at that year’s MTV Video Music Awards ceremony.

The ‘Girl, so confusing’ remix was borne out of a long-held belief shared by fans that Lorde and Charli were not on speaking terms.

Last month, Lorde spoke about joining Charli on the remix. “When I was writing this verse, I was saying these things to her for the first time,” Lorde added.

“There was such a rawness and an immediacy to what I was saying. I love that we truly did work it out on the remix. There’s something very brat about that, something very meta and modern. Only Charli could make that happen.”

Last Friday’s ‘Guess’ release also saw the donation of 10,000 undergarments used in its music video to non-profit I Support The Girls.
