Fox announced on Saturday that Kara DioGuardi is now officially out as a judge on American Idol, leaving Randy Jackson as the only original member of the panel.  Kara was gracious and upbeat as she confronted reporters and called her Idol experience "amazing".  Show producer Simon Fuller says that he will continued his professional relationship with the songwriter, who still had a one year option on her contract that Fox didn't exercise.   Rumors still are flying that Steven Tyler and Jennifer Lopez are the front runners for the new spots on the staff, but Fox is surprised that so many of you have actually petitioned for my inclusion on the show by contacting them at headquarters by E-mail and even phone calls.
