Lorde has confirmed her new single Green Light is all about heartbreak – so who is the man behind it?
The song's ferocious lyrics allude to a partner's infidelity and delve into the emotions of trying to move on from a break up.
"It's totally a song about heartbreak. I've never been really good at writing songs about relationships," she told ZM's Fletch, Vaughan and Megan.
"It's more about finding yourself through that situation. You go through the thing and it's so awful and you just wish you could let go. The green light thing is saying 'I'm not okay right now but I'm going to be okay'."
The timeline of the song's conception indicates that Green Light could be about photographer James Lowe – Lorde told Zane Lowe (no relation) on Apple Music's Beats 1 that she began writing for Melodrama 18 months ago, around the time of her split from Lowe in early 2016.
James and Lorde were together for around three years before their split. A number of Lorde's Instagram posts featuring Lowe have been deleted.
She was later rumoured to be seeing Universal Music promotions director Justin Warren, who denied the claims, saying the pair were good friends.
So it seems lyrics like "Those great whites, they have big teeth/Hope they bite you/Thought you said that you would always be in love" are addressed to Lowe.
Lorde – real name Ella Yelich-O'Connor – described Green Light as a "curve ball", and that Melodrama will be a "very diverse" album.
