Following this, the 19-year-old Grammy-winner posted a chic selfie of herself with her chopped-brunette tresses, writing as the caption, "Miss Me?"

Billie isn't a stranger to experimenting with different hairstyles.

The artist has sported neons, pastels, and her signature two-toned black-and-green tresses before.

While the change was a big surprise, Billie's newest appearance was well-received by her peers and fans.

Olivia Rodrigo commented, "Omg" while model Chase Keith joked, "Is this me?"

The singer seems to be making a lot of changes before 2021 closes out.

Recently, the My Future singer dished on her secret tattoos during a sit down interview with Vanity Fair, despite previously promising no-one would "ever see it."

"I have three tattoos now," Eilish revealed in the interview. "I have one here that says 'Eilish.' Yes, I love myself."

They say blondes have more fun, but Billie is sure to prove everyone wrong.
