With Charli XCX and Billie Eilish’s remix for ‘Guess’, it’s now a sapphic brat summer.

On 1 August, Charli released a new version of her addictive club banger, which features on the deluxe edition of her viral sixth studio album BRAT, with the ‘Lunch’ singer contributing flirtatious lyrics such as, “Charli likes boys but she knows I’d hit it” and “Charli, call me if you’re with it”.

The equally iconic music video, directed by Aidan Zamiri, starts with Charli performing the first verse at a raucous underwear party, before Eilish (literally) crashes into the building on a tractor.

After Eilish slays her verse, the duo strut down the street and take the party to an underwear pyramid/mountain. (Think Kylie Minogue’s ‘All the Lovers’ but with bras and knickers.)

The ‘Guess’ remix and video was met with overwhelming praise – especially from sapphics, who have “combusted” over their chemistry and Eilish continuing to be unapologetically queer in her lyrics.

“Billie and Charli rolling through a mountain of bras and panties! Oh this is a lesbian fever dream,” one fan wrote on X/Twitter, while another tweeted: “What a moment to be a queer woman who enjoys pop music.”

The undergarments in the video have reportedly been donated to ‘I Support the Girls’, an organisation that “collects and distributes essential items, including bras, underwear, and menstrual hygiene products, allowing women and folx experiencing homelessness, impoverishment, or distress to stand tall with dignity”.

‘Guess featuring Billie Eilish’ follows previous remixes from ‘BRAT’ such as ‘Von Dutch’ with Addison Rae and A.G. Cook, ‘360’ with Robyn and Yung Lean and ‘Girl, So Confusing’ with Lorde.

BRAT was met with widespread critical acclaim and has become the 16th highest-rated album of all time on Metacritic, as well as Charli’s first top three entry in the U.S.

Various singles have started climbing worldwide charts and earned viral status, particularly ‘360’ and ‘Apple’, the latter of which spawned a dance craze on TikTok.

The sound, aesthetic and impact of the album has led to ‘brat summer’ a way of life that Charli explained as: “You’re just like that girl who is a little messy and likes to party and maybe says some dumb things some times.

“Who feels like herself but maybe also has a breakdown. But kind of like parties through it, is very honest, very blunt. A little bit volatile, does dumb things. But it’s brat. You’re brat. That’s brat.”

All hail brat summer!
