Before we could even finish emotionally processing the fabulousness that was her pastel hair, Katy changed her outfit – and hairstyle – for her powerful performance at the award show. She replaced her short purple bob with a sleek, long, all-black ponytail that had us totally confused.

As it turns out, Katy's purple locks were actually a really convincing wig, and her dark hair was tucked up underneath it. She sure made us do a double take with this style!
