As day two of Coachella wrapped in Indio, California last night, many of the top stars in attendance—including both performers and VIP guests alike—made their way to the private Guess Jeans compound for a private after-party. In a sea of after (and after-after) parties happening in and around the Coachella festival grounds, the Guess affair was the after-party: This year, Charli XCX hosted the big blowout bash, which also saw stars like Anya-Taylor Joy, Timothée Chalamet, and Justin Bieber make an appearance.

Inside the private Guess house, the invite-only crowd mingled while sipping craft cocktails by Patron El Alto and Gin & Juice. In one corner, fashion It girls like Alex Consani, Julia Fox, Richie Shazam, and Cara Delevingne gathered under the open-air cabanas, while Hollywood A-listers like Joy, Chalamet, and Leonardo DiCaprio congregated in another buzzy corner. (All keeping a low profile, of course.) Naturally, some buzzy music names were also in the mix: The Dare, Troye Sivan, and Clairo were among those in the starry crowd.

As the evening progressed, Charli XCX—fresh off performing on the Coachella mainstage with special guests like Sivan, Lorde, and Billie Eilish—took to the DJ booth with her fiancé, George Daniel, for a special intimate set. Naturally, even the coolest of party guests couldn’t help letting loose when the pop star spun her own songs, including “Guess.” (A fitting song choice, given the denim brand hosted the bash.) A mini private Coachella performance for some of her closest friends? Very brat of Charli.
