American Idol Finale ~ Mariah Carey Medley by HumanSlinky

As part of the two-hour "American Idol" finale Thursday night (May 16), judge Mariah Carey sang a medley of some of her biggest hits -- though we were sad "Someday" did not make the cut.

However, viewers were in an uproar on Twitter over Carey appearing to be lip-synching during the pre-taped segment.
