Here are a few things we know about Justin Bieber’s forthcoming Purpose album: the standard track list includes 14 songs, the deluxe edition has 19 songs, and the singles “Where Are U Now,” “What Do You Mean?” and “Sorry” will all be included. What we don’t know, aside from a “What Do You Mean?” remix featuring Ariana Grande, is who else will appear on the album, as the official track list has yet to appear.

Fans of Halsey should start getting excited, though, because Scooter Braun is teasing a Bieber/Halsey duet on Purpose. And hey, Braun would know—he’s Bieber’s manager!

Halsey got in on the tease soon after Braun’s tweet, posting “Lol I know the feeling.....” in response. Fans will have to wait to actually hear the duet when Purpose drops on Nov. 13.

Thursday (Oct. 22) was a big day for both the Biebs and Halsey: the former released new single “Sorry,” and the latter announced a headlining show at New York’s Madison Square Garden next August. Halsey’s debut album Badlands was released in August, and we wrote about why she matters a whole lot in the world of popular music.
