Charli XCX Drops Billie Eilish-Assisted "Guess" Remix and Video

Brat Summer continues.

Months after releasing her chart-topping sixth studio album, Charli XCX blessed fans with the official remix of “Guess”—the infectious dance track that appeared on the deluxe edition of Brat—and its electric music video.

Charli teased the release on social media this week when she posted on Instagram and called on fans to guess the featured artist. Although the black-and-white photo didn’t show any faces, people quickly determined that Charli had teamed up with Billie Eilish. And how did they come to that conclusion? They noticed that the mystery guest was rocking a set of rings that Billie often wears.

Turns out the fans were right. Charli returned to IG several hours later to preview the Aidan Zamiri-directed visual for the “Guess” remix. The clip begins with Charli asking, “Hey Billie, you there?” before she enters a relatively bare room and asks, “You wanna guess?” The video then cuts to Charli and Billie collapsing on a pile of bras, quite the omen for a visual absolutely packed with undergarments. (There's an entire mountain of them.) On Instagram, Zamiri revealed the shoot went down mere days ago, on July 28.

All of the many, many pieces of underwear in the video were subsequently donated to I Support the Girls. The organization obtains and gives out "essential items, including bras, underwear, and menstrual hygiene products, allowing women and folx experiencing homelessness, impoverishment, or distress to stand tall with dignity.”

Billie spoke about the Charli collaboration during her recent interview with Zane Lowe alongside her brother/producer, Finneas.

“I did a session with another artist for the first time in six years, a couple weeks ago," she said. "And it was really fun, and I was really nervous ’cause I haven’t worked with anyone but Finneas in six years. And I hated it back in the day. I really, really hated it. I hated studios, I hated collaborating. I’ve never done a feature.”

Finneas chimed in, "This was, to me, such a fun part of being in the music business. Billie was sitting and telling me why she loved this one artist. We were watching their music videos together, and I know them, and I was texting them, and I was like, ‘We’re sitting here watching your stuff. It’s so good.’ They were like, ‘I’m in LA.’ I was like, ‘Do you want to do a day?'” Finneas then added through laughter, “Billie tried to get out of it like three times.”

You can watch the official “Guess” remix video via YouTube above and stream the song now on Spotify, Apple Music, and all major platforms.

The release comes less than three months after Billie shared her third studio album, Hit Me Hard and Soft, which debuted at No. 2 on the Billboard 200. The Grammy-winning artist will support the project with a North American tour, which kicks off Sept. 29 in Québec. The trek will include stops in Toronto, Detroit, New York City, Atlanta, Portland, and Chicago before wrapping up on Dec. 17 in Inglewood, California.
