Lorde claims her recording sessions are being plagued by ghosts.
The 'Royals' hitmaker is currently working on her second album but called a halt to production after strange noises kept showing up when she listened back to her music.
She tweeted: "ghosts in the studio don't want us to record tonight, they leaving their ghost hum on everything. buzzzzzzzzzzzzzzzz (sic)"
Lorde recently revealed her new material will be "totally different" to the tracks on her debut, 2013's 'Pure Heroine'.
She said: "I think I've learnt so much as a songwriter, there's going to be so much of an improvement because of that.
"I'm working on stuff quite tentatively, it's definitely still at the beginning and yeah, it's totally different. I wrote the last album about that world which was the suburb where I grew up and populated by my friends and people who were really familiar to me. Now I'm in a different place every day and I'm with new people every day and it's a different vibe."
The 17-year-old star has also admitted she is unsure she will still be popular in years to come.
She said: "Since I started making music, a lot was made of how old I was and it made me think about, what happens when I'm 25? Will people still like what I'm doing? Will it still be important if I'm not this hyper-youthful being?
"It's stupid, I know I'm being silly, but I can't help it. It's just one of those things. I'll get over it."
