Christina Aguilera Welcomes Gwen Stefani to The Voice Family

Christina Aguilera would give up her seat on the judge's panel

The Voice has finally found its newest judge! Since the rumors first started that mom-to-be Christina Aguilera would give up her seat on the judge's panel to Gwen Stefani, the show's producers have refrained from confirming the move. 

But Aguilera did it for them. 

"So excited to have you join #TheVoice squad @GwenStefani! Welcome to our crazy fam! Kisses xoxo #blondesdoitbetter," th, who will take a break from the show to welcome her daughter with fiancé Matt Rutler, Tweeted on Tuesday. 

Shortly thereafter, Stefani finally confirmed the not-so-secret news. 

"It's true! gx @nbcthevoice," Stefani wrote as an Instagram caption to accompany a shot of her doing the show's signature peace sign, while holding a mic. 

Stefani, who will take a seat next to veteran judges Adam Levine and Blake Shelton, won't be the only newbie on the block: Pharrell Williams will be taking over for CeeLo Green. 

And while Shelton has already sized up the competition, Daly is looking forward to Stefani's influence over the contestants. 

"She's friends with the other coaches but has a strong opinion, which is also important," he said. "They can't all just be too lovey out there. So I think she'd be a solid choice."
