Aguilera returns to The Voice as a coach for season 8 after missing two seasons. The other coaches include Adam Levine, Blake Shelton and Pharrell Williams. Paul Telegdy, president of alternative and late night programming for NBC entertainment:
We are excited to welcome Christina back to her red chair and can’t wait to see how she mixes things up among Adam, Blake and Pharrell, in what will be an incredibly competitive competition. These four talented artists are at the top of their game as musicians and as coaches. The mentoring is sure to be intense and the stakes will be high.
