Perhaps the biggest pull of The Voice is its premise of choosing contestants solely based on their voice, and not what they look like. But when 14-year-old Levi Watkins took the stage, the judges were shocked to see the person behind his smooth vocals.

Watkins performed Train's "Hey, Soul Sister," with his own breezy twist. His belt during the chorus caught coach Blake Shelton's attention and he turned his chair, snagging the teenager for his team.

When the other coaches turned around, their jaws hit the floor. "A baby!" John Legend shouted in disbelief as Kelly Clarkson remained speechless.

"I am not an actor, but that was the greatest performance I gave in my life," Shelton jokingly admitted. "To turn around and not react was the hardest thing I ever did."

Clarkson went on to note that she has never been "that thrown" in her five seasons as coach. "For a billion dollars, I thought you were a female that sang lower and in your 20s," she revealed, before telling Watkins that he has a "really cool vibe."

Shelton accepted his victory by slamming the other coaches for making "the worst move of your entire Voice careers" by not turning around.
