The full album appeared online on multiple streaming and torrent download sites this afternoon leaking all 11 tracks ahead tomorrow's official release date.
It's a massive blow for the Kiwi pop star who, until now, has been working tirelessly to keep her new tracks under wraps only playing the album for a select few including her team, family and some fans who were invited to listening parties on Wednesday in Auckland and New York.
Lorde's label Universal Music have declined to comment and Lorde has not yet posted anything to social media on the leak.
Fans who heard the album at the exclusive listening parties described it as "heartbreaking but beautiful".
One fan who heard the album has declared: "It will blow minds."
The listening session in New York last night saw just 50 people get to listen to the album, mostly fans who responded to a tweet asking them to email her requesting tickets to the event.
The reviews were overwhelmingly glowing.
One called it a "heartbreaking but beautiful body of work," while another called it "glorious".
