The Final Four Perform To Be Named 'The Voice'

The finale four performed not once but three times to be called this season's winner of 'The Voice,' including a holiday classic and a coach duet. Blake Shelton teamed up with Barrett Baber and Emily Ann Roberts for two country classics, 'Rhinestone Cowboy' and 'Islands in the Stream.'

Barrett Baber - Die A Happy Man

Barrett Baber used his wife and child as inspiration for Thomas Rhett's 'Die A Happy Man.'

Coach Blake Shelton felt the performance. "I've never worked with someone who laid their heart on the stage as much as you."

Loved hearing it! #VoiceFinale https://t.co/3bMfJRqCXB

Emily Ann Roberts - Burning House

Emily Ann Roberts closed the show by switching things up. Known for singing country classics, Roberts chose to sing Cam's current hit 'Burning House.'

Pharrell only had one word after Roberts' performance "flawless."

"If anyone can pull an upset, it was that right there," coach Shelton told Roberts to end the show.
