It doesn't come to anyone's surprise to hear that Christina Aguilera is a diva on the set of her hit show "The Voice". From Chicago Sun Times:
While "The Voice" is a solid hit, a couple of key staff members of the talent showcase wish they didn't have to work with judge Christina Aguilera — who one TV pro on the show says, "takes 'diva' to a whole new level."
The source, who has worked with some of the biggest musical stars on the planet, insists Aguilera "is by far the most difficult. She's constantly demanding, never appreciative of anything and just plain nasty."
