The Bury a Friend singer took to the site with a snap showcasing her newly-dyed blonde hair and, in the caption, she teased a new project was imminent.
Alongside the photo, in which the star wore a cream coloured cardigan with her hair styled with bangs and loose curls, the star penned: “things are comingggg.”
Billie didn’t share any further details.
The post comes after the Bad Guy hitmaker’s brother and collaborator Finneas told reporters at TMZ he “cannot confirm or deny” the singer is working on new music.
Billie, 19, released her debut album, When We All Fall Asleep, Where Do We Go? in 2019.
