Billie Eilish is known for her iconic hair colors. For so long, she had pale blue hair, and she’s been rocking neon green roots for a while now, but the ‘do she just shared on Instagram might be her most shocking look yet.

To help promote Justin Bieber’s new album Changes, Billie took to Instagram, posting a video of Justin talking about the need to “protect” Billie. The craziest part of the post, though, comes when you swipe through the carousel.

Yup, it’s a photo of a young, blonde Billie Eilish, rocking a Justin Bieber tank top.

The photo is so unexpected, not only because it’s rare to see Billie with a standard hair color, but also to see her in a tank top, as opposed to her usual baggy tee shirt or sweatshirt.

The post gets even better as you keep scrolling, though. We get to peek a look at Billie’s childhood room, which was literally covered in Justin Bieber posters. She even had a personalized sign that read, “Forever Believer! Billie’s Room.” I mean, I knew Billie was a fan, but this is just beyond.

All together, it was an incredible Instagram post, and now I can't help but hope Billie's next hair color is blonde because she's totally rocking it.
