Next week we’ll find out who will become The Voice. In addition to learning who America votes the winner of Season 3, the show will up the star power.

Rihanna, Bruno Mars, Kelly Clarkson and The Killers are slotted to perform next week as the final three show off their talents and the results are aired during the two-night finale.

Trevin Hunte said his goodbyes earlier this week. Clearly upset, a teary-eyed Trevin was thankful for the experience he gained this season.

“Words can’t even explain how happy and excited I am. I definitely got an opportunity to start my career and show America that I’m more than just The Voice,” he said.

Calling the show the “best experience for me in my whole entire life,” viewers have seen Trevin transform into a confident performer.

“I’ve grown as a performer, I’ve grown as a person,” he said. “I never saw myself getting a chair to turn around so to make it to the Top 4 was a great accomplishment for me. I don’t think I would have done anything different. I feel like if I had done anything different I wouldn’t be Trevin.”

Nicholas David, Cassadee Pope, and Terry McDermott are the final contestants left.
