The Voice has announced the star-packed guest line-up for next week’s season 5 finale, and there are some exciting names in the mix.

The Voice season 5’s winner will be announced Tuesday, Dec. 17 during the two-hour finale. In addition to contestant performances, some special guests will be stopping by to lend their talents to the show as well.

Lady Gaga will take the stage with R. Kelly to perform their new single “Do What U Want” off of Gaga’s album ARTPOP. Gaga and Kelly have recently performed this song (quite memorably) on Saturday Night Live and the American Music Awards. They likely would have to tone down the performance a bit for the family-friendly show.

Celine Dion and Ne-Yo will perform their duet, “Incredible,” from her new album, Loved Me Back to Life. The unlikely pairing of the Canadian songstress and the R&B hit-maker should make for a memorable performance, plus Dion is always pretty entertainingly nutty.

One Republic will perform the song “I Lived” from their album Native. Additionally, lead singer Ryan Tedder, who served as Team Adam’s mentor this year, is also The Voice‘s in-house songwriter-producer, and will be writing an original single for the season 5 champion, to be performed after his or her victory moment.

The final three contestants were revealed this past week: Team Christina’s Jacquie Lee, and Team Adam’s Tessanne Chin and Will Champlin. Blake Shelton has finally been unseated as the winning coach for the past three seasons, as his final contestant, Cole Vosbury, was eliminated.

Other celebrity performers for The Voice finale are set to be announced over the next several days.

The Voice performance finale airs Monday, Dec. 16 at 8 p.m., and the season 5 live finale will air on Tuesday, Dec. 17 at 9 p.m. on NBC.
