Lorde stars in the music video to her latest "Yellow Flicker Beat," and she got all dressed up in a half-dozen ways for you.

Or is it for her? The New Zealand songwriter turns 18 tomorrow and is celebrating in all manner of style, for a song that was made for "The Hunger Games: Mockingjay - Part 1." Some of it, she's rocking dress for a ball. Most of the rest of the time, though, she's like a rare spirit that wanders the night in some unisex button-downs and a red get-up that will have you watching Prince videos. She's personifying her own protagonist of the song, without nary a Katniss to be seen.

"Yellow Flicker Beat" sits on the "Mockingjay" tracklist besides new songs from Chemical Brothers with Miguel, Pusha T, HAIM, Major Lazer with Ariana Grande, Charli XCX, Grace Jones, a Kanye West remix and more. The soundtrack will be out on Nov. 17, while the Jennifer Lawrence-starring film hits theaters on Nov. 21.
