NBCThey say two heads are better than one, and occasionally two voices are also better than one.
The Voice contestants are set to prove that tonight when they perform duets, both with their coaches and with celebrity musical guests, for part one of the NBC hit's season nine finale.
E! News can exclusively reveal those celebrity guests, and we can assure you that we are jealous of at least a couple of them, including a former coach!
Blake Shelton's two remaining team members, Emily Ann Roberts and Barrett Baber, will, of course, be breaking out some country hits.
Emily will be joined by Ricky Skaggs to sing "Country Boy," while Barrett will be singing "No One Else on Earth" with Wynonna Judd.
Gwen Stefani's finalist Jeffrey Austin will get to sing "Hollow" with Tori Kelly, while Jordan Smith, Adam Levine's contestant who is the frontrunner heading into the finale, will get to perform "Without You" with help from Usher. Yes, the former coach is returning to take the stage, and yes, we are very excited. (Usher served as a coach in seasons four and six, and his contestant Josh Kaufman won the sixth season.)
So does Jordan have this season in the bag? "I think it's obvious that Jordan's the best singer on the show and it would be a lie not to say that," Barrett told E! News at the beginning of the season. "He's consistently delivered the most amazing performances I think the show has ever seen."
As for Jordan, he was quick to praise all the "special people" competing this season, saying, "There's so much individuality. All of these singers have their own signature sound and I think it just proves that what society is looking for—something that's different, something that's exciting."
The Voice finale kicks off tonight at 8 p.m. on NBC.
(E! and NBC are both part of the NBCUniversal family.)
