Lorde is "about to show you the new world."
The "Royals" singer shared a lengthy update to Facebook on Monday, a day ahead of her 20th birthday, wishing her teenage years farewell -- as well as teasing the long-awaited followup to her debut album, Pure Heroine.
"Tomorrow I turn 20, and it’s all I’ve been able to think about for days," she wrote. "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."

"Sometime in the last year or so, part of me crossed over," she explained. "For one thing, I made a very deliberate choice to withdraw for a little while from a public life ... I turned inwards to my friends, my family, towards this moment, so I could learn more about who I was, and 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," Lorde continued, describing the experiences she's had throughout the year. "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. I was reckless and graceless and terrifying and tender. I threw sprawling parties and sat in restaurants until the early hours, learning what it’s like to be an adult, even talking like one sometimes, until I caught myself. All I wanted to do was dance. I whispered into ears and let my eyes blaze on high and for the first time I felt this intimate, empire-sized inner power."

"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," she said, before offering a bit of a glimpse into her timeline with regard to new music.
"I just need to keep working a while longer to make it as good as it can be. You'll have to hold on," she cautioned. "The big day is not tomorrow, or even next month realistically, but soon. I know you understand."
"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," Lorde revealed. "What i'm trying to say is: this is a special birthday. The party is about to start. I am about to show you the new world."
