Are the lyrics from 'Royals' engrained in your frontal lobe? Now you can add a few more lines from Lorde into that mix.

The teenage New Zealand songstress has been posting vague photos and messages this week as she's been working in the studio on what could possibly be the much anticipated follow-up to her 2013 debut, 'Pure Heroine.'

She just posted this photo on Instagram with the message, "first line":

This comes after a few other status updates including the one directly below that was captioned: “i always remind myself to bring a candle for the studio and finally i did today and ohhhhhhh”:

Of course, Lorde is also curating the soundtrack to 'The Hunger Games: Mockingjay -- Part 1,' so the lyrics and studio time could just be for that.

Either way, she's embarking on a run of U.S. tour dates beginning tonight (Sept. 5) in Philadelphia. Get her full schedule here.
