The "Roar" singer posted a new snap showcasing her much lighter eyebrows via Instagram on Thursday.
Wearing her hair in two green pigtail buns, fake eyelashes and long pink nails, the singer looks almost unrecognizable in the candid shot.
Perry captioned the picture, "BAUS BISH BB." We're not sure what the strange new look is for -- maybe for the "Dark Horse" singer's next music video?
Nevertheless, Katy's not the first pop star to rock the bleached eyebrow trend. Miley Cyrus showed off her lightened eyebrows on her Instagram page last year, which ended up just being a temporary look for her shoot with W magazine.
