Are Charli XCX and Billie Eilish collaborating on 'Guess' remix?

Charli XCX has sparked speculation that Billie Eilish might be featured on a remix of her track "Guess" from the album Brat. 

On Wednesday, Charli XCX shared a social media post with a photo captioned “Guess ?” showing herself with another artist whose face was obscured. The image had the text: “Guess featuring” followed by a series of blanks.

Fans have noted that the rings worn by the hidden artist resemble those worn by Billie Eilish during her recent appearance on Amelia Dimoldenberg’s “Chicken Shop Date.” 

Despite these hints, Charli XCX has not confirmed the identity of the featured artist or the remix's release date. However, she hinted last week that something might be coming this week.

Charli XCX’s album Brat, released in June, has gained viral traction, fueling the "Brat summer" trend. The album’s distinctive neon-green, all-lowercase cover has been widely emulated, including by Vice President Kamala Harris, who updated her campaign's X (formerly Twitter) profile to match the album's aesthetic. 

Charli XCX endorsed Harris's campaign with the post: “kamala IS brat.” The “Brat summer” phenomenon, described by Charli XCX as a blend of confidence and attention-seeking style, has influenced both fans and celebrities alike.

The album has seen significant success on streaming platforms, with “360” climbing to No. 27 on the U.S. Spotify chart, and “Apple” making a notable jump to No. 53. 

The Brat album also secured a spot at No. 8 on the U.S. Spotify albums chart for the week ending July 25.
