Lady Gaga’s stunning new hair will have you turning your joker face.

The A Star Is Born actress debuted an applause-worthy hair transformation as she arrived Sept. 25 at the London premiere of her new film Joker: Folie à Deux. 

On the red carpet, Gaga unveiled her new hair: a bob-length crimson ‘do with dark undertones that matched her floor-length, mermaid style red gown with large shoulder pieces. She accentuated the Harley Quinn-inspired look with turquoise eye shadow, a yellow gold and platinum brooch and jewelry from Tiffany and Co.

After showing some PDA on the red carpet with fiancé Michael Polansky, Gaga opted for a quick change at a fan event later in the evening, complementing her mullet-like style with a tan and navy dress and black-and-white checkered leggings that channeled her Joker character.

The hair transformation is on brand for the “Just Dance” singer, as she felt her role as Harley Quinn in the film (out Oct. 4) opposite Joaquin Phoenix’s Arthur Fleck (aka The Joker) required her to explore a new side of herself and her voice.
