The former Voice coach had more to say about her qualms with the NBC singing competition, telling W magazine: "I signed on to a show where the blind audition element was something interesting, something genuine.

When I stop believing in something, then it's like, 'What am I doing here?'" ALSO: Aguilera says her departure had nothing to do with Gwen Stefani.
