Ariana Grande's gone grey, and she's not afraid to Instagram about it.

The Dangerous Woman singer, who's typically deferred to a signature brunette or blond ponytail, has thrown her Instagram followers for a loop by debuting a brand new silvery (but not silver, she's quick to say!) mane.

"btw i (it's grey)" she wrote with the caption above, in which cartoon hearts float up and out of her new locks. And fans seemed to be very much on board with the change.

"i’m speechless you’re so beautiful," one wrote, while another noted "i loooove your hair like this."

Ari most recently switched up her hairstyle a year ago, when she debuted darker braids that substituted for blond locks she'd been sporting for months.
