LOS ANGELES (AP) -- Ellen DeGeneres is glad that her "American Idol" debut drew big ratings and high praise from the show's creator, media mogul Simon Fuller. But the real test, she says, was judging herself.

She realized she didn't let the contestants down, DeGeneres said Wednesday, the day after she watched the broadcast of her first "Idol" episode.

DeGeneres said she was concerned going into the show that she would tiptoe around the truth with the aspiring pop stars. But she realized she'd been truthful without being too blunt.

Fellow judge Kara DioGuardi told a teleconference Wednesday, before tonight's "American Idol" episode on Fox, that DeGeneres did "an incredible job for the first time here."
