While we've been seeing a lot of Hilary Duff recently—did you see that bikini selfie? Yeah, hiii—we did not ever expect to see her without her trademark blonde hair. And yet, today, what do we find when scrolling through Instagram?

This!

Last night, Hilary was, as she puts it, "turned into a mermaid." How Kylie Jenner of you, Hil! She paired her brand new hue with an entirely white outfit, which made it pop that much more. It's unclear if Hilary totally ditched blonde—her hair does kiiiinda look brunette on the top now, but it could just be her filter choice—or just decided to dabble in teal dip-dye.

Let Hilary's new hair, much like her bikini selfie, serve as a reminder that she's not a regular mom, she's a cool mom. Maybe the coolest mom, TBH.
