Jennifer Hudson among performers added to 'The Voice' season 14 finale

NBC has added four additional performers to Tuesday's "The Voice" season 14 finale, including Jennifer Hudson before she returns to the singing competition full-time this fall. So who else is coming to an already star-studded final episode, and what will they be doing?

Per the network's press release on Monday, Hudson will be the celebrity duet partner for Team Blake finalist Kyla Jade as they cover Hudson's song "I Don't Know Where I've Been." It's a fitting choice because also according to the release, Jade was one of Hudson's back-up singers before she auditioned for "The Voice." It's also a nice bit of buzz for Hudson before she returns to coach "The Voice" season 15. NBC has made a habit of promoting coaches before their arrivals or returns to their big red chairs, such as how Miley Cyrus was the knockout rounds mentor in season 10 before she became a coach in season 11.

Kane Brown will serve as the celebrity duet partner for Team Blake's other finalist Spensha Baker. If that name sounds familiar; it should; he just performed on "The Voice" last Tuesday. You can watch his semifinals performance of "Heaven" by playing the video above. Brown and Baker will perform his single "What Ifs" before Brown hits the road as the opening act for country star Chris Young; tickets for their tour are available through AXS at the bottom of this article.

Like Brown, Julia Michaels was already on "The Voice" this season as the battle rounds advisor for Team Adam. Since there are no Team Adam finalists in "The Voice" season 14, Michaels is working with Team Kelly finalist Brynn Cartelli for a medley of Michaels' songs "Jump" and "Issues." That might provide some deja vu for "Voice" fans because the latter song was covered on the show just two months ago by contestant Miya Bass.

Rounding out the new arrivals is Ryan Adams, who will turn his single "To Be Without You" into a duet with Team Alicia's Britton Buchanan. Music fans can get tickets to see Adams live at Colorado's Red Rocks Amphitheatre on Thursday, June 14 now through AXS.

"The Voice" finale airs Tuesday at 9 p.m. on NBC. Music fans can see Kane Brown live as he opens for Chris Young this fall, with tickets on sale now through AXS using the links below:
