Jennifer Hudson delivered an outstanding performance at Sunday night's Super Bowl, but American Idol music director said the singer had lip-synched the national anthem.

American Idol music director Ricky Minor, told The Associated Press that, at his request, Hudson lip-synched the anthem to a previously recorded track.

This was such an important performance, because it's the first time everyone has seen Jennifer. But she's in such a great place, with such great spirits, and time can heal her wounds. She's on fire right now and totally grounded, said Minor.

Hudson's performance followed a tribute to the crew of U.S. Airways Flight 1542 and a performance of America the Beautiful by Faith Hill, who reportedly also lip-synched the song.
