Jennifer Hudson -- Liar, Ingrate?

Jennifer Hudson has been trash-talking "American Idol" and dissing on Simon Cowell. But the video evidence makes it clear -- the Dreamgirl is dreaming it all up.

"EXTRA" rolled back the tapes of Hudson on "Idol," and Simon clearly gave her props throughout the season, saying that she was a "front-runner" and calling her "great" multiple times -- high praise from the often harsh Cowell.
