The Grammy-winning singer wrote a lengthy Facebook post that is titled "A Note From The Desk Of A Newborn Adult" which is a letter to her younger self and was posted on the eve of her birthday as she turns 20 on November 7. "Tomorrow I turn 20, and it's all I've been able to think about for days," Lorde wrote at the beginning of her letter.

The singer-songwriter, was only sixteen when she came to the music recording scene with her first album. On her post, she said, "I was 16 when most of us met. Can you believe it? I laugh thinking about that me now - that glossy idiot god, princess of her childhood streets, handmade and ugly and sure of herself. All my life I've been obsessed with adolescence, drunk on it. Even when I was little, I knew that teenagers sparkled." At the age of seventeen, she had her first number one hit with the song "Royals."

Last year, the singer made a conscious effort on staying out of the public eye as said on her letter.She stated, "Sometime in the last year or so, part of me crossed over. For one thing, I made a very deliberate choice to withdraw for a little while from a public life." The singer mentioned on the post that she turned to her family and friends to learn who she really was and she continued saying,"so I could let this new project show itself to me."

"And oh my god, it was a colossal year! One for the ages. I maxed out every single emotion I have in the best possible way, the colours still aching behind my eyes like this weird blissful hangover," as she described her experience for the past year. "My heart broke. I moved out of home and into the city and I made new friends and started to realize that no-one is just good or bad, that everyone is both, I started to discover in a profound, scary, blood-aching way who I was when I was alone, what I did when I did things only for myself."

"And then I wrote a record about it, all of it, so much more than what I've written down here, and I'm in New york getting it done. And tomorrow, I'm not a kid any more," as the singer reveals what inspired her to write her next album recounting her discoveries about herself. Lorde also said that her first album "Pure Heroine" paid tribute to her glorious teenage years. She noted, "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 -" For her next project, it is still under wraps and she says, " You'll have to hold on. The big day is not tomorrow, or even next month realistically, but soon. I know you understand." Towards the end of her letter she says that the party is about to start and continued saying, "I am about to show you the new world."
