The show has a slight twist -- the auditions are based purely on the voice, without seeing the potential contestant perform. Aguilera revealed she was drawn in by the concept. "It's so easy to judge people on how they look or walk or talk and this one is specifically about the voice."
Christina also experienced her share of judgment based on her rough start in 2011 with her Super Bowl flub, Grammy stumble, and arrest earlier this month, but the singer says she remains grateful. "All of my experiences in the past year, and everything that's happened to me, I thank God for it."
She added, "You have to take the good with the bad and you have to take the bad with the good. If you're in this business, if you're in the spotlight, you have to be able to take criticism and you have to take the punches along the way."
The singer's 3-year-old son, Max, also joined his mother on "The Voice" set. " He's got a thing for it. He definitely wanted to come to work with mommy."
Other coaches include Maroon 5's Adam Levine, country music artist Blake Sheldon, and Grammy winner Cee Lo Green. Aguilera recalled Cee Lo's flamboyant Grammy outfit and exclaimed, "Oh my God, Cee Lo is amazing!"
The show's creator Mark Burnett chimed in and raved about his new panel of coaches on the show. "I am so blessed and so grateful. On a level of capability they're all very experienced, they're all stars, and all have a ton of fans."
