Millie Bobby Brown looks unrecognisable after major hair transformation

She looks incredible!

The Stranger Things actress shared a selection of images on her social media of her new look.

The 20-year-old, who got married to Jon Bon Jovi's son Jake Bongiovi last year, is one of Gen Z's biggest fashion icons, and for good reason.

Taking to her Instagram, Brown revealed that she has gone back to blonde.

Fans took to the comments section of her post to share their thoughts on her major transformation.

One person put: "UM DEVOURED!? ATE!? FEASTED!? COOKED!?"

While another said: "Omg she looks so pretty."

"THE BLONDE HAIR IS BACKKKKKK," a third penned.

A lot of fans also pointed out that the choice of hair colour is perfect if she was going to play pop icon Britney Spears.

A second said: "Oh s**t. Is she actually playing Britney?!"

"U better be playing Britney," another said.

"The exact shade to play Britney," another agreed.

Although fans are purely speculating whether Brown is set to play the 'Toxic' singer, a Britney biopic has been confirmed.

Universal won the rights to her memoir, The Woman in Me, last year after a highly competitive auction.
