Christina Aguilera, Adam Levine, Blake Shelton and Cee Lo Green paid tribute to the victims of the Newtown school shooting with a special performance of Leonard Cohen's “Hallelujah” last night on The Voice.

Xtina and company were joined by host Carson Daly, Christina Milian, finalists Cassadee Pope, Nicholas David, and Terry McDermott, as well as other former contestants, and they each held a card with the name and age of the twenty children and six adults that were killed in last week's horrific shooting.

The show will crown their season three winner tonight, and The Killers, Bruno Mars, Kelly Clarkson and Rihanna are set to perform.
