All four celebrity coaches came together for the last time this season, singing Green Day's "Good Riddance (Time of Your Life)" on The Voice Season 3 live finale tonight, Dec. 18, 2012.

Christina Aguilera, Adam Levine, Blake Shelton, and Cee Lo Green sounded great as always, but it was more than just a solid performance. When The Voice returns on March 25, 2013, Xtina and Cee Lo's seats will be taken by Shakira and Usher. It was a bittersweet sendoff for the two celebrity coaches, who left their hearts on the stage they've called home for three action-packed seasons. We don't know about them, but we certainly had the time of our lives!
