Adam Levine & Blake Shelton Are Out Fishing In New ‘The Voice’ Promo Before Singing ‘Reunited’ [VIDEO]

They'll be reunited! The original vocal coaches for NBC's 'The Voice' are returning for season 5 this month and they're all featured in a new promo for the show's return harmonizing together on the 1978 classic 'Reunited'.

The Peaches & Herb tune is originally started out by Adam Levine, who's on a boat fishing with Blake Shelton, then Shelton joins in with a few words and both are stopped when they hear the voice of Christina Aguilera. The two turn around to see her walking on water in a beautiful red dress then she's joined in by Cee Lo Green and some mermaids as he rises up out of the water like Neptune.

Finally, Carson Daly shows up with a yacht to get the coaches and Cee Lo has the final words with, "Now that is ridiculous."

The Voice returns Monday, September 23rd on NBC.
