Billie Eilish is switiching up her hair again, and fans are loving it.
She debuted a new hair color that has many people predicting that the singer's next era may be upon us.
In an Instagram photo, the "Bad Guy" singer revealed that she traded in her brunette locks for a jet-black dye job, which is reminiscent of her early 2019 style.
The photo appeared to be taken inside a plane and depicts Billie sitting in her seat while wearing an equally dark face mask. She captioned it with a simple black square.
Eilish also left another comment under the photo saying, "she's back."
Since posting, Eilish's new hair reveal has been liked more than 9 million times.
This is the latest transformation for the chameleon-like pop star, who seems to casually update her look every couple of months.
In December, Billie showed off a brand new caramel-colored shag cut, revealing that shade was the closest she'd been to her natural hair color for quite a while.
Before that, she said she was secretly a redhead for a week after transitioning from the platinum blonde bob she rocked starting in March 2021 and for the June 2021 cover of British Vogue.
