NBC announced it yesterday that Aguilera is getting her old job back, reported Ace Showbiz.
"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, NBC Entertainment's president of alternative and late night programming, 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," Telegdy added.
