Gwen Stefani is giving back her red chair to Christina Aguilera for the upcoming season of "The Voice," but the "Used to Love You" singer is returning to the show, not as a coach, but as an advisor to one of the teams.

It has been confirmed that Stefani will be working with boyfriend Blake Shelton's team as an advisor for the 10th season of the NBC singing competition show, and the two recently sat down with Access Hollywood to talk about her return to the series.

Shelton revealed that it was his plan to bring back Stefani for season 10, saying, "You start thinking like, who are the ultimate artists out there that you can get to mentor your team," he said, while smiling and looking at her.

"I can actually see her somewhere and be like, 'hey!' So I don't know, it worked out," he continued.

The country star also said that they collaborate well as coaches, which made the decision to pick her as his group's mentor the natural choice for him.

The couple sat down for their first interview as a couple, constantly looking and smiling at each other throughout the interview, and at one point the 39-year-old turned to the No Doubt frontwoman while saying, "And she's so smart, and talented."

The 46-year-old returned the compliment, saying that Shelton is "really good at what he does" and that it was fun to work with him on the show.

Shelton said that the best piece of advice that he can give to an artist is to figure out what they love about what they do, saying that he learned that along the way.

Stefani playfully asked, "Is that why you have 21 hit singles in a row?"

Shelton replied, "And that's why you're a future Rock and Roll Hall of Famer."

Season 10 of "The Voice" premieres on NBC on Feb. 29.
