Lorde’s Pure Heroine follow-up album is reportedly expected for release in 2017, and she continues to tease it on social media.

NME reports that it will come before a world tour and festival dates.

To tease the album, the singer posted a photo of Apple ear buds to Twitter and wrote, “listen to the record on these every day,” adding, “wanna hear it exactly how you will.” She did not reveal either the release date or the title of her impending album.

Lorde also recently celebrated her 20th birthday, and wrote an emotional letter to fans on the occasion, calling herself a “newborn adult.” She has remained relatively quiet in the industry since releasing Pure Heroine, which chronicled the pitfalls of fame and became an instantaneous hit for anyone wanting to rebel against celebrity materialism.

In the letter to fans, she describes the new album as a saga of her move to New York and the heartbreaks that can come along with that.

“I wrote a record about it, all of it, so much more than what I’ve written down here, and I’m in new york getting it done,” Lorde wrote in the letter. “this record - well, this one is about what comes next.”

She further wrote, “The big day is not tomorrow, or even next month realistically, but soon. I know you understand. The part is about to start. I am about to show you the new world.”

In addition to the letter to fans, Lorde also celebrated with a lavish birthday party thrown by bestie Taylor Swift in New York’s Soho neighborhood. The gathering also included celebrity friends Lena Dunham, Aziz Ansari, Karlie Kloss, Mae Whitman and Rachel Antonoff.
