4. Christina Aguilera jams with Jimmy Fallon
Christina Aguilera doesn’t need a stage, backup singers or proper instruments to kill performance. The little diva with the huge voice made music in Jimmy Fallon’s office! Jimmy got so into the jam session that he busted out a few dance moves.
Christina plays something of a black widow the actual video for "Your Body", where she murders her lovers mid-hookup. The poor guys never see it coming in the visual below!
