Demi Moore debuts platinum blonde hair for new movie role in Brave New World

Demi Moore has traded in her luscious brunette locks for a brand new role.

Moore, 57, debuted her shoulder-length platinum blonde hair for her part in Brave New World in a recent Instagram post.

"Meet Linda. #BraveNewWorld is streaming now on @peacocktv!" Moore captioned the photo on July 15 (US Time).

At this point, it's unclear whether this is Moore's bleached hair or if she's wearing a wig for the character.

Moore's daughter, Tallulah Willis, expressed her excitement over her mother's new look in the comments section.

"LINDAAAAAA," she wrote. "WE STANNNNN LINDA. Tbh you blonde is a whole new truth I didn't know I needed."

Celebrity stylist Brad Goreski wrote, "Ohhhh she's BLONDE! Werk!"
