In an interview with Rolling Stone, she said: "And then I dyed my hair blonde and I was immediately like, 'Oh, I don't know who I am'."

As People.com reports, the glamorous look aligned with the softer feel of her sophomore album, 'Happier Than Ever,' but ultimately, it felt like too much of a deviation from Eilish's true self.

Eilish's brother and collaborator, Finneas O'Connell, said in the profile, "In a strange way, it was like being in a tornado basement, like reading a lovely little story."

"It was a coping mechanism for an album."

Eilish shows off her new icy blonde hair in a March 2021 Instagram video.

She made her Met Gala debut six months later in a peach tulle Oscar de la Rente corset ball gown, with her blonde hair styled into a glamorous bob.
