Charli XCX has shared yet another Brat remix, enlisting tourmate-to-be Troye Sivan for an update of the album track “Talk Talk.” That’s not all: A new, 16-track album add-on called Brat and It’s Completely Different but Also Still Brat will follow on October 11, via Atlantic. The new disc features today’s remix, 11 more mystery tracks, and the four other remixes released this year: “360 Featuring Robyn and Yung Lean,” “Von Dutch A. G. Cook Remix Featuring Addison Rae,” “Girl, So Confusing Featuring Lorde,” and “Guess Featuring Billie Eilish.” Check out the artwork and new song, which has a cameo from Dua Lipa speaking French and Spanish, below.

The Charli XCX & Troye Sivan Present: Sweat Tour kicks off in Detroit this weekend. The “1999” and “2099” collaborators are joined by Shygirl on the dates, which take them across North America this month and next.
