Katy Perry

 , also known as Evan, was one of the original judges and a co-host of Music Mania. She served as the executive producer of the series and was said to have created the modern format, first used in Music Mania 2. Out of the three judges, Katy was the most critical, but used harsh crtiqiues in order to help the acts improve. When asked about the ratings success of Music Mania, Katy remarked how proud she was of the series and that she planned to continue it well into the future. Unfortunately, due to a family emergency, Katy stepped down from the panel before Season 5 and was not replaced. She later competed in Music Minis: Oops!... I Did It Again where she placed 9th, after being eliminated by eventual winner and future judge Gwen Stefani.
