Yet another music legend is joining NBC singing competition "The Voice" as an adviser, with Celine Dion set to mentor members of coach Gwen Stefani's team during the show's upcoming 12th season.

Dion broke the exciting news herself on Twitter, telling followers that she would be #TeamGwen during the show's next round of Battles. The superstar tweeted that she was "very excited" for the gig.

Stefani and Dion also appeared on the Today Show to promote their team-up, revealing a bit of the dynamic that will make their collaboration tick. (Namely, Dion sings like an angel -- sometimes nonsensically, and pretty much nonstop -- and Stefani laughs and smiles in awe.)

"There is nobody like Celine," Stefani gushed to the Today cameras, adding that the goofy Dion brought a great energy to the set.

"Her brain -- it's crazy inside there, and it's awesome," the singer told Today.

For her part, Dion said she was looking forward to working on "The Voice," and exposing herself to new styles and different artists.

"Even though I've been in the business for so long, I'm still learning," she explained.

Dion has been busy as of late, recently announcing a new tour and revealing that she's once again collaborating with Disney, with the contribution of a brand new song to the soundtrack of the upcoming live-action remake of "Beauty and the Beast." We can't wait to see her on our TV screens, too.

"The Voice" returns for season 12 on February 27 on NBC.
