American Idol: Katy Perry on Going All Out for Ursula Transformation on Disney Night (Exclusive)

ET was backstage with the judges to get their take on the eliminated contestants. 'American Idol' airs Sundays and Mondays on ABC.

Katy Perry is so silly ❤ Why are people hating? If many of you actually watched American Idol you would see she is the biggest sweetheart.

[@kursten4501]

Because shes clearly on drugs or drunk. This isnt normal behavior.

You go girl don’t listen to the haters

[@karenhardie1132]

Thought the costume was great. Judges do need to give some criticism once in awhile. Everyone gets a standing ovation and is wonderful. Simon is missed because he was honest.

[@Derexican]

I used to "like" Katy Perry....now I can't even pretend to "like" her....how sad. The new American Idol is a travesty....Lionel Richie is the only good thing about it but the format of the show makes even him not enough of a good thing

[@eliseobolanos7634]

Hahahaha she didnt like you either

[@LyricsThatFly]

American idol is being cringy lately

[@leonaleona1628]

I agree. Katy was super annoying. At least the talent is amazing!

[@amour.desire.valentinel9456]

[@paulsmith3778]

Whatever happened to Katy Perry ? The hair , the personality? After " Roar" something happened to her. Not for the better. People ask me who I think in celebs are really good looking. I used to say Katy Perry" Are you crazy? She's beautiful! .....No more. Sorry

[@patryx3905]

Thats just a costume lol the theme was “Disney”. She started wear long hair again.

[@VossYeti]
