Kelly Clarkson reveals what Blake Shelton has to do if she wins 'The Voice' (exclusive)

It wouldn't be a competitive season of The Voice without a side bet from the coaches.

This season, Kelly Clarkson reveals how high the stakes are between she and longtime pal Blake Shelton. In the latest batch of outtakes from the show, Clarkson reveals that Shelton will have to call her "Queen" if one of her artists wins.

"We made a bet. He has to call me Queen Kelly Clarkson," she explains, garnering enthusastic approval from team mentor and former Team Blake winner, Cassadee Pope. "Like, 'Yes, queen. No, queen.'"

Elsewhere in the blooper reel, "Shufflin" Shelton returns to show off his hilarious victory dance moves, while he and Adam Levine sweetly hug it out during a particularly stressful moment.

The Voice airs Mondays and Tuesdays on NBC.
