"The Voice" season 5 premieres Monday, September 23 at 8 p.m. ET on NBC, and the original gang is back. Season 4 coaches Shakira and Usher have finished keeping the spinning red chairs warm for returning coaches Christina Aguilera and Cee Lo Green.

The battle round mentors for the upcoming season of "The Voice" have been announced ahead of the official season 5 fall premiere. Team Christina will be accompanied by British singer-songwriter Ed Sheeran. Team Adam Levine is recruiting Grammy award-winning singer-songwriter Ryan Tedder of OneRepublic. Team Cee Lo will receive counsel from R&B artist Miguel. Finally, the most recent winning coach, Team Blake Shelton will join forces with music icon Cher, who performed during the "The Voice" season 4 finale.

"The Voice" promo released this week gives viewers a taste of the unified coaches. Reunited and it feels so good. Watch the season 5 promo to see Christina strut on water, Cee Lo emerge from the sea with a trident, and the budding bromance between Adam Levine and Blake Shelton get nautical. It seems Christina, resembling a smashup of Jesus and Marilyn, is returning with a shorter 'do. The universe is in balance, though, seeing as Adam Levine compensated with a newly grown beard.

Watch "The Voice" premiere September 23 on NBC to see the clique together again on the reality singing competition.
