Charli XCX has released another Brat remix. This time, she’s enlisted Billie Eilish for a new version of the bonus song “Guess.” The new song comes with a video directed by Aidan Zamiri. It features a ton of underwear and also a cameo from the producer of “Guess,” the Dare. Watch the “Guess Featuring Billie Eilish” video below.

All of the undergarments featured in “Guess Featuring Billie Eilish” have been donated to I Support the Girls, an organization that, according to its website, “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 a spate of Charli XCX remixes, all with long titles: “The Von Dutch Remix With Addison Rae and A. G. Cook,” “The Von Dutch Remix With Skream and Benga,” “The 360 Remix With Robyn and Yung Lean,” and “The Girl, So Confusing Version With Lorde.” The original “Guess” featured on the deluxe version of Brat, titled Brat and It’s the Same but There’s Three More Songs So It’s Not.
