Over the weekend Eilish took part in a Q+A via her Instagram Stories, which saw her reveal some information about her follow up to 2019's When We All Fall Asleep, Where Do We Go? debut album.

A fan asked Eilish how many tracks will feature on her second album, leading Eilish to respond with a list of numbers from one to 16.

Eilish hasn't announced her second album yet, but in a recent Vanity Fair video interview, Eilish did discuss how her creative process has changed since her debut album, "Honestly, everything is different. Like, we really haven't done anything the same, we haven't made any of it in the same place, we've grown so much in just the way we create, i've been writing so much more, and, honestly so much better than I ever have I feel. I feel like a different person, like, I really couldn't be happier with what I've been creating, and couldn't be prouder of myself than I am about what I feel that I have created."

Last month Eilish and Rosalía released their long-awaited collaborative track "Lo Vas A Olvidar".
