None of the four judges on TV\'s \"American Idol\" will be asked to return next season, The Wrap reported Thursday. Randy Jackson, Keith Urban, Nicki Minaj and Mariah Carey are the panelists for the current, 12th season of the Fox singing competition series. \"All four are gone,\" an insider told The Wrap. \"They feel they\'ve lost their core audience and they want it back.\" The entertainment news website said a Fox representative declined to comment for its story.
