The Voice has unveiled its season 12 guest advisers, and it's an impressive roster, with Celine Dion, John Legend, DJ Khaled and Luke Bryan all on board.

Dion will serve coach Gwen Stefani's team, Legend will work with Adam Levine's squad, Khaled will offer some major keys to Alicia Key's pupils, and Luke Bryan will support his friend and fellow country superstar Blake Shelton's roster.

The announcements came Friday through a number of media channels. Dion and Stefani appeared on the Today show to discuss their partnership. In their interview, Stefani said getting Dion on her team was "the prize" and was sure to upset the other coaches.

Meanwhile, Keys and Khaled also were on the TV circuit and joined Extra to announce the producer and all around inspirational figure's addition to the show.

"I feel like it’s so incredible to have the diversity that I’m able to bring to the show, especially through Khaled," said Keys. "I feel like there's so many ways to look at music, there’s so many ways to create. It’s not just about being a great performer, it’s about being a personality and for the energy that you bring to come out. And I think that is what Khaled does very naturally."

For his part, Khaled naturally promised to bring positivity to his role.

"If the room is dark, I’m the lightbulb," he said. "I try to bring the best out of the people I work with."

The Voice's 12th season debuts Feb. 27 at 8 p.m. on NBC.
