The next season of The Voice will debut September 10th on NBC and in the new promo teasing the show, the four vocal coaches demonstrate that they'll go to great lengths to discover new talent, including beating each other up.

The promo for the show takes place in a hotel and shows Christina Aguilera sitting in the lobby and hears a distinct voice of a voice coming from a shower somewhere in the hotel.  She races up the stairs but is stopped by Blake Shelton, who gets shut down by Adam Levine who ends up being karate chopped by Cee Lo Green.

Eventually all four bust into the room of Bruce Jenner who comes out of the bathroom in a robe displaying his Olympic gold medal and delivers this line to Cee Lo Green,

Cee Lo, this is how you do bling!"

Check out the trailer for the return of The Voice on NBC.
