A bearded Adam Levine breaks into song in a fishing boat with a flannel-clad Blake Shelton. Christina Aguilera, who was notably missing last season, emerges from the woods as a cross between Marilyn Monroe and a nymph, interrupting the bromance and joining her costars in song. Cee Lo Green, not to be outdone, and also returning after a break last season, rises as Poseidon flanked by mermaids.
Carson Daly, who will continue as the show's host, shouts "Ahoy, coaches!" from a yacht, completing the reunion. The American reality vocal competition will return to NBC on September 23rd.
