With the season premiere of NBC's "The Voice" less than a month away, the network has finished revealing which music stars will serve as Season 12's celebrity advisors. Per the series' Facebook page, Celine Dion, John Legend and DJ Khaled will join the previously announced Luke Bryan in assisting contestants during the battle round phase of the singing competition, which should air in late March or early April.

Dion will consult for Team Gwen, as Gwen Stefani returns to the show as a coach after serving as an advisor herself during last fall's Season 11. One of the most notable and most successful female singers in any genre, Dion will certainly be an asset to the pop singers - especially female pop artists - that Stefani tends to recruit. Dion has also maintained a long-running residency at Caesars Palace in Las Vegas, which she'll be able to cross-promote since she has concerts scheduled for most of the spring. She performs on select evenings from February 1 to June 3; click here for show dates and tickets.

Legend will be the advisor for Team Adam. He has some experience in the singing competition world, since he stood in for Lionel Richie on the short-lived ABC reality series "Duets" four years ago, and also appeared on Spike's celebrity series "Lip Sync Battle" with Common. Having been able to create soulful and emotionally resonant music while also crossing over with pop artists like Meghan Trainor (with whom he performed the hit "Like I'm Gonna Lose You"), Legend should be a great fit for Levine's team, which tends to be the more cerebral of the four "Voice" rosters. With his own smarts and charisma, Legend could also be a candidate to fill in if any other coaches choose to take a season off as "The Voice" will reach its six-year anniversary by the time Season 12 ends.

That leaves DJ Khaled to work with the artists on Team Alicia after a busy 2016 that he can certainly keep going by appearing on "The Voice." Khaled released his ninth studio album Major Key in July and also wrote his first book. He's already tweeted that he's working on his tenth record with the likes of Mariah Carey, Justin Bieber and Travis Scott, though he may now best be known for appearing in commercials for tax preparation software Turbotax.

With the blind auditions starting in late February and lasting anywhere from a month to six weeks, fans should expect to see Dion, Legend, Khaled and Bryan on "The Voice" in March or April. If you can't wait until then for more on Season 12, you can use the media player included with this article to watch a teaser.

"The Voice" premieres Monday, Feb. 27 at 8 p.m. on NBC.
