The Paramore singer debuted a brand new look on "Late Night With Seth Meyers" on Wednesday.
The 25-year-old, who is known for her multicolored mane, took her trademark tinted tresses to a whole new level by adding blue and green streaks to her edgy bob.
Though we love Hayley's newest hair hue, we can't help but wonder if the look's only temporary.
On Thursday, after a fan tweeted, “New photo of @yelyahwilliams! Really love her new hair style!,” the "Ain't It Fun" singer re-tweeted a photo of herself sporting a simple green-blonde 'do, captioning the pic, "Wut new hairstyle?"
If her new look is the real deal, it's definitely a different look for Hayley, who has rocked a variety of wild styles and has dyed her mane red, orange, yellow, pink, and blue.
