Lorde has been listening to her new album through Apple earphones so she knows what it will sound like for her fans.

The 'Royal' hitmaker has shared a picture of the white earpiece on her Twitter and hinted that her follow-up to 2013's debut 'Pure Heroine' is nearly finished.

She captioned the photo: ''listen to the record on these every day. wanna hear it exactly how you will (sic)''

Lorde previously teased new music in a heartfelt letter to fans to mark her 20th birthday.

The British singer - who turned 20 on November 7 - has produced ''the best lyrics'' she's ever written and is desperate to release her second record.

The lengthy post titled 'A Note From The Desk Of A Newborn Adult' shared on her Facebook page begins: ''Tomorrow I turn 20, and it's all I've been able to think about for days.''

It goes on to reveal: ''Writing 'Pure Heroine' was my way of enshrining our teenage glory, putting it up in lights forever so that part of me never dies, and this record - well, this one is about what comes next.

I want nothing more than to spill my guts RIGHT NOW about the whole thing - I want you to see the album cover, pore over the lyrics (the best I've written in my life), touch the merch, experience the live show. I can hardly stop myself from typing out the name. I just need to keep working a while longer to make it as good as it can be. You'll have to hold on. The big day is not tomorrow, or even next month realistically, but soon. I know you understand.''

Her letter came after a fan took to Instagram earlier this year and moaned about how long it is taking for her to release new music.

The furious star replied: ''Give up on me if you want to! I'm an artist, I write a record when I have enough special stories to tell, and it's all me, every melody every lyric, not some team who just start the machine up every eighteen months like clockwork.''
