Lorde has spent three days alone in the wilderness looking for inspiration.
The 'Royals' hitmaker has made some "exciting breakthroughs" in the follow-up to her 2013 LP 'Pure Heroine' after taking a helicopter to a secluded place so she could write without interruption.
She tweeted: "took a helicopter out into the wilderness spent 3 days alone writing and made some of the most exciting breakthroughs on this record so far (sic)"
Earlier this year, Lorde joined David Bowie's former touring band for a moving rendition of his track 'Life on Mars' at the BRIT Awards, which took place a month after he died of cancer at the age of 69.
And the 19-year-old musician was incredibly nervous before taking to the stage, so tried to pretend she was singing directly to the iconic star.
In Twitter posts, she previously revealed: "I was so nervous in the wings, and then i whispered to myself 'just sing it to david', and nothing else mattered ... Such an honour getting to perform #BRITs2016 paying tribute to my hero (sic)"
Lorde was backed by Mike Garson on piano, Gail Anne Dorsey on bass and Gerry Leonard and Earl Slick on guitars - all of whom played with Bowie on his 'A Reality Tour' in 2003 and 2004 - for her sombre cover which was preceded by a medley of Bowie's major hits, including 'Space Oddity', 'Rebel Rebel' and 'Under Pressure'.
Before the New Zealand songstress sang, Annie Lennox delivered a moving speech to the pop legend and Bowie's friend Gary Oldman accepted the BRITs Icon Award on his behalf, praising him for his "superhuman potential" and "remarkable music".
Lorde had been personally selected by Bowie's estate as she had been one his favourite new artists in the years leading up to his passing.
The pair met when she was just 16 at the 'Aladdin Sane' star's request at a 2013 benefit honouring actress Tilda Swinton.
