Gwen Stefani is joining the voice with Pharrell Williams as coaches. The new duo are joining Adam Levine and Blake Shelton in the big red chairs on the popular singing show.

The Voice's Instagram page posted a photo of the four with the caption, "First look: Season 7 #HOLLA."

Stefani is following in the footsteps of former coaches Christina Aguilera and Shakira; she also shared a photo of herself outside the studio on Tuesday on her Instagram, along with the caption "#workingit on the set."

Pharrell Williams, who worked with the No Doubt singer on her 2004 hit song "Hollaback Girl," said on the Today show back in May that working together again was "magical."

"It's serendipitous," Pharrell said. "We've always had a special connection."

The Voice returns on Sept. 22 to NBC.

Stefani's husband Gavin Rossdale says that his and Stefani's marriage remains 'rock solid' after 12 years of marriage and three kids, according to Us Weekly.

Rossdale said, "We have so many kids now, no matter what, it's rock solid." The rocker couple are parents to three sons, Kingston, 8, Zuma, 5, and Apollo, 3 months.

"He's 3 months old so he's pretty chilled out," Rossdale said of newest addition Apollo. "We're very proud of him. He's a great kid [but] he'll be naughty soon enough."

When asked about Zuma and Kingston, Rossdale joked, "Oh, they're terrible! So naughty!"

Rossdale also recently joked to E! that he and Stefani don't find time together.

"We don't, it's perfect. That's why we've been together for so long," he shared his secret to a long marriage to E!.

"To be with one person for a very long time actually gets more interesting," Rossdale told E! News at The Bling Ring premiere last year. "I'm into that. She's a great girl. I'm lucky."
