'The Voice' Final Performance Videos: Who Will Win Season 3?

'The Voice' Final Performance Videos: Who Will Win Season 3?

It's the final week of "The Voice's" third season, with the final three contestants -- Cassadee Pope, Terry McDermott and Nicholas David -- singing their hearts out in hopes of winning America's vote.

Monday's show opened with all four coaches and host Carson Daly joining the season three contestants to sing "Hallelujah" in remembrance of the victims of the Newtown, Conn. shooting. Each person held a sign with a victim's name and age on it.

After that somber moment, it was time for the show to begin with Cee Lo Green's Nicholas David. David, who said he's chosen songs with a message all season, sang "Great Balls of Fire" and "Fire" -- accompanied by real fire. Levine said he's glad that David went lighter and had fun tonight. "Your fire burned this house down," said Green.

Blake Shelton's Cassadee Pope decided to sing -- again -- "Over You," the Miranda Lambert cover that put her at No. 1 on Country Digital Songs and No. 25 on the Billboard Hot 100 after selling 152,000 downloads in its first week according to Nielsen SoundScan. The coaches all praised her fancy dress and her amazing voice.

Terry McDermott and his family got to visit Shelton at his home this week. McDermott and Shelton teamed up to sing "Dude Looks Like a Lady" with a "special guest" on guitar. That special guest happened to be a wig-wearing, shirtless Adam Levine.

David continued his preacher-in-training regime with "Lean on Me." Green said he appreciates him so much and loves his energy. "I believe in you, you make me believe," he said.

McDermott was the next to sing a solo, with "Broken Wings." Levine said that it was clear something was going wrong mechanically in the beginning, and McDermott nodded his head in agreement. But Shelton pointed out that the type of singing that McDermott does is very difficult, and he respects him for it.

Pope teamed up with Shelton next to sing "Steve McQueen." It was fine, but you know what Pope should never do? Sing through a megaphone.

McDermott revisited "I Want to Know What Love Is" next. The king of the '80s hits continued his reign with this one. Christina Aguilera praised his work ethic, and Shelton said he thought McDermott's latest performance of the track was even better than the first time.

David teamed with Green for "Play That Funky Music," which was fitting since they are the leaders of the funk movement on this show. But what really stood out about this performance was the mini-Cee Lo that took the stage. His name was Milo. That's all we got to know about him.

Pope closed out the show. She revealed that her father contacted her, and that they have spoken about reconnecting. She sang "Cry" for her final performance. Pope has always excelled with emotional songs, and this was another powerful performance from her. "I've never heard you sing as good as you've seen tonight, and that's saying a lot," said her coach, Shelton.
