According to TMZ, a rep for Hudson confirmed that the singer cancelled because she felt that producers didn't give her enough time to learn the music. This came as a surprise as all of the performers received their prepared music at the same time.

Jennifer's rep also says the producers "completely understood" why Jennifer would not be performing, but other reports claim that producers were caught totally off-guard. Jennifer had been paid upfront upon agreeing to perform, and there's no word yet on if the rumored six-figure fee will have to be returned.
Ne-Yo ended up taking Jennifer's spot to close out the show with a bang.
