And doesn't the 18-year-old, Maleficent actress look a-to-the-mazing?
Elle, who is the younger sister of I Am Sam actress Dakota Fanning, is in good company with her new choice of hair colour.
Yes, we know pink has been doing the rounds on the celebrity circuit for a fairly long time now, but it shows no sign of going away. And when it hits the likes of Amber Le Bon and Bella Hadid you know it's reached a whole new level of cool.
Elle's soft, pastel tones were created by her go-to hair guru and celebrity colourist Jenna Alcorn of Ramirez Tran Salon in Beverly Hills, Los Angeles.
Jenna coined the colour: "Pink Panther" on her Instagram feed on Monday (11 July) while Elle went for: "dusty [rose emoticon] hair."
Us? We're going for rose gold all the way.
This new look is a big change for the 18-year-old who is known for her baby blonde locks.
But we don't reckon she's regretting it for one single second and we can't wait to see what kind of outfits the fashion-forward actress pairs it with.
Elle has just finished promoting her new movie, The Neon Demon in which she plays an aspiring model who moves to LA and becomes the latest It girl.
The film features some major beauty-inspiration including chunky halo braids, glitter tears and fluoro face gems. And if Elle's new do is anything to go by we can expect much much more to gawp at in 2016.
