Perry, 27, has apparently reverted to her 2010 look, sporting bright blue hair as she posed with a fan Thursday in Santa Barbara, where she's filming an Adidas commercial.
Though the pop star shied away from the People's Choice Awards earlier this week (she still came up a big winner), she appeared to be in good spirits interacting with her admirer.
