XCX's new album is not ready yet. But after an EP in 2016 ("Vroom Vroom") and a mixtape ("Number 1 Angel") early this year, the british singer-songwriter has been teasing us with tweets of a dream-team of collaborators from a new "imagined" mixtape, such as Carly Rae Jepsen, CupcakKe, Kim Petras, Tove Lo, ALMA, Caroline Polachek, Brooke Candy, Pabllo Vittar, Tommy Cash, Dorian Electra, Mykki Blanco, Jay Park and MØ. Turns out it's not a dream. "Pop 2", the new mixtape is arriving this December 15th.
