Charli XCX Taps Into Big Brat Energy at All-Star 32nd Birthday Party With Billie Eilish and Lorde

Charli XCX‘s big Brat summer marches on. The singer whose album title attitude and color scheme have been eagerly adopted by Vice President Kamala Harris’ presidential campaign — and plenty of others — celebrated her 32nd birthday in style on Saturday night (August 3) in Los Angeles.

According to reports, Charli’s A-list crew for the night included Twisters star Glen Powell, as well as Anya Taylor-Joy, Rosalía, Addison Rae, the Haim sisters, Sabrina Carpenter, Gracie Abrams, Rachel Sennott, Tove Lo, Finneas, Lukas Gage, Scout and Tallulah Willis and Nelly Furtado, among many others. But it was drop-bys from some of her musical collaborators that got Brat nation worked up.

According to fan-shot video of the night out, Charli and Lorde hopped up on couches to dance and sing along to the remix of Charli’s Brat anthem “Girl, so confusing,” with Charli clearly living it up in shades, tiny black shorts and a white shirt with a strategic cut out in front to show off her black bra. Lorde, also dressed in black and white, danced like everyone was looking, shouting the lyrics alongside Charli as the two danced hip-to-hip and hugged it out.

Billie Eilish also dropped by the party in Silverlake to dance and sing along to the pair’s just-released “Guess” remix, with Billie rocking an oversized baseball jersey, lime green bandana and red-tinged shades for the party, where one of the gifts included a beautifully Brat-propriate bouquet of Calla Lilies mixed with cigarettes from Rosalía.

Charli’s U.S. Brat tour is slated to kick off on Sept. 14 at Little Caesars Arena in Detroit.
