• Billie Eilish revealed a new hairstyle on Wednesday after two years of sporting green roots.

Billie Eilish debuted a brand new hairstyle on Wednesday, ditching her signature bright-green roots.

The 19-year-old singer posted a video on Instagram, which shows her flipping her light-blonde hair over her head. The new style also includes a fresh, shaggy cut with bangs.

About 13 hours before, Eilish teased a new dye job on her Instagram story, asking fans, "can you guess what color?"

She captioned her video, "did you guess correctly?"

Eilish's brother and producer, Finneas O'Connell, reposted the video on his own Instagram story.

"Beginning of a new era," he wrote.

The "Bad Guy" singer also posted a photo of herself shortly after the video, captioned, "pinch me."

It's possible that Eilish is wearing a wig. However, she previously told fans she would dye her hair after the February release of her documentary, "Billie Eilish: The World's a Little Blurry," after some teased her for keeping the green for two years.

"This is the longest I've had the same hair color since I was 13 & that's on mental stability and growth," she commented on Instagram.

"I'm changing it after the doc comes out," she added. "It'll be the end of an era, I'ma give you a new era... I have announcements to make, I got some shit to put out."

Eilish is expected to release her sophomore album later this year. She recently told Vanity Fair that she has 16 songs in the works.

"We've been working," she said, referring to herself and her brother. "And I love them all."

"I think Finneas and I have just seriously really gotten in the groove. We do it so fast," she continued. "There was a period of time, a month ago or something, we were just texting the label like, 'Song done, another song done, another song done.'"

Eilish and O'Connell each won two Grammy Awards on Sunday: best song written for visual media for "No Time to Die," the new James Bond theme song, and record of the year for "Everything I Wanted."
