Pharrell Williams and Christina Aguilera are to return as coaches for Season 8 of the singing competition The Voice, NBC announced Tuesday.
The Season 7 newcomer and original show mentor will work alongside the previously announced panelists Adam Levine and Blake Shelton early next year.
Shelton and Levine have been with The Voice since the show began in 2011. Aguilera most recently appeared in Season 5.
"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," Paul Telegdy, president of alternative and late night programming for NBC Entertainment, said in a statement. "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."
