With the Barbie movie fast approaching, the cast has been providing us with all the Mattel doll vibes – from Margot Robbie to Dua Lipa and even Kourtney Kardashian, we cannot get enough of the pink! But today, the celebrity who falls prey to our love and admiration today is Billie Eilish for her stunning blonde hairstyle.

Teasing her new and soon-to-be-released song for the film, Billie took to Instagram with a short video post, writing: "TOMORROW🥳🥳". And while we, ofc, are constantly refreshing our feeds for the ballad's launch, what has us a little preoccupied is the singer's totally new rockabilly bangs.

Prepare to hark back to the golden age with said 'do...

Category is: vintage chic. *Chef's Kiss*

As shown, Billie's hair has been styled into a sleek high ponytail, finished with full, flicked-up ends. But the star of this look has to be her micro-fringe. But this isn't any old micro-fringe.

Said fringe is also widely known and recognised as Bettie Bangs (after iconic pin-up model Bettie Page); it was hairstyle hugely popular in the 1940s and 50s. Thanks to the way it has been rolled upwards, the fringe only hits halfway down Billie's forehead, placing it in micro-bangs territory.

Everyone's clicking on...

Take another look at the style with the still shot the star shared just yesterday:

"“What Was I Made For?” SONG AND VIDEO COMING THIS THURSDAAAAAAYYYYY!!!!! EEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!! i caaaaaaaan’t wait to see what you think😋🎀 !! that shit hurted 😅," she wrote.

Oh, and did we mention she's blonde?!

Bye bye, brunette, for it seems Barbie Bills is here to stay slay.
