Loving that attention to detail.
Kristen revealed her bedhead-bleached do in New York last month, but with her hair hidden underneath a beanie, and her face concealed behind a pair of sunnies, it was practically impossible to see her new platinum locks.
We've been waiting with baited breath ever since to check out the Twilight star's rock 'n roll hair makeover and finally, on Monday, she revealed it on the red carpet at this year's Costume Institute Gala at the Metropolitan Museum of Art in New York City.
Along with anyone who's anyone in the world of fashion, film and music, Kristen joined the likes of Kylie Jenner, Kim Kardashian, Beyoncé, Rita Ora and Lady Gaga in all their finery at this year's super-glamorous do.
And while silver dresses were the colour trend of the night, Kristen chose a black, zip-up Chanel number with metallic accents.
Her hair was totally on point for the event, with the top twisted up into a quiff and the sides tightly braided over her ears. And as well as her rocking hair, we fell in love with Kristen's eye-popping make-up.
Most A-listers opted for the usual red lips (or super-dark, berry in the case of Taylor Swift and Miranda Kerr) and smoky or bronzed eyes, but never one to follow the crowds, Kristen went for futuristic eye make-up, with silver metallic, squared-off shadow on her eyelids.
To copy her look, we love Illamasqua Pure Pigment Eye Shadow in Ara, £17, illamasqua.com.
Use a thin, eyeliner brush like the NYX Pro Brush 11, £8.50, boots.com to create your angled outline, then fill in your eyelids and finish with mascara and black eye pencil both above and below your lashline.
Chanel dress, totally optional, of course!
