Hailee Steinfeld Sends Fans into a Frenzy with New Blonde Look at 2021 Met Gala: 'Angel'

Hailee Steinfeld has gone blonde!

The 24-year-old actress and artist debuted a new look at the Metropolitan Museum of Art's Costume Institute Gala on Monday, surprising fans with a platinum bob and light eyebrows to match. Steinfeld stepped out in a glittering beige slip Iris Van Herpen dress with radiant, petal-shaped panels and matching Jimmy Choo platforms for fashion's biggest night.

In 2019, the "Most Girls" singer wore one of Viktor & Rolf's meme-inspiring gowns — stitched with the words "No Photos Please" — with a black hair bow, Judith Leiber camera-shaped clutch and Harry Winston jewelry. And in 2018, she rocked a simple white Atelier Prabal Gurung gown with high slit and ruffled train, plus a crown and pearl-and-diamond jewelry by Tasaki and Jimmy Choo heels.

Earlier this year, Steinfeld opened up to PEOPLE about being in the spotlight for a decade, after finding fame at 13 in True Grit alongside Jeff Bridges.

Though she's nearing her mid-20s, the star said she definitely missed out on some typical teenage milestones because of her upbringing.

"I remember all my friends were going to a winter formal or a home­coming dance, and I was either at home or work­ing," she says, adding, however, she feels she "definitely made up for it" by attending star-studded premieres, awards shows, and events.
