Christina Aguilera will return to 'The Voice' USA next year.

The 'Your Body' hitmaker, who previously shared a rotating spot on the judging panel with Shakira, has been replaced by Gwen Stefani this season as she is taking some time off after welcoming her daughter, Summer Rain Rutler, into the world in August, but has already signed on to appear on the next series alongside Adam Levine, Pharrell and Blake Shelton.

Producers confirmed the 33-year-old singer is officially returning to the NBC musical competition for season eight via Twitter today (14.10.14), writing: "OFFICIAL ANNOUNCEMENT: Say HELLO to your Season 8 coaches! @adamlevine @Pharrell @xtina @blakeshelton #TheVoice."

A source recently claimed Christina was upset about Gwen filling in for her and was concerned she wouldn't be asked to return to the show.

The insider said: "Christina is extremely threatened by [her temporary replacement] Gwen. She knows that if the ratings are higher on Gwen's season than they were on hers, the producers may have no choice but to ask Gwen to stay on. Christina's in a world of paranoid right now."

But the blonde beauty previously insisted she was very excited about Gwen, 45, joining the show after she accidentally leaked the information in April.

She tweeted at the time: "So excited to have you join #TheVoice squad @GwenStefani! Welcome to our crazy fan! Kisses- xoxo #blondesdoitbest [sic]."
