It was an unprecedented beauty look for the famous brunette, and in an emotional YouTube live stream, Katy later explained her motivation for making the chop. "People like talk about my hair, right? They don't like it or they wish that it was longer. I so badly want to be Katheryn Hudson that I don't even want to look like Katy Perry anymore sometimes. That is a little bit of why I cut my hair, because I really want to be my authentic self."
