The "Firework" singer is reportedly being paid $25 million by ABC for the gig, but that huge fee has reportedly come with some conditions attached.
A source revealed to RadarOnline.com: “They want a more modulated and thoughtful Katy. It’s not like they’re asking her to change her hairstyle or revise her style team, but they are asking her not to upstage the contestants the way some past judges, especially Mariah Carey, had the tendency to do.
“They want the show to be disciplined and taken as seriously as the Oscars instead of taking on the circus atmosphere that has made The Voice such a big hit.”
One idea being floated is that the audience would see Perry, 32, judging the show in just her sweat pants or dressing gown.
This would show her in a more down-to-earth style as opposed to her often over the top "glam queen" image.
After landing the judging spot on AI she said: “I am honored and thrilled to be the first judge bringing back the American Idol tradition of making dreams come true for incredible talents with authentic personalities and real stories.
“I’m always listening to new music, and love discovering diamonds in the rough — from mentoring young artists on my label, or highlighting new artists on my tours, I want to bring it back to the music."
