The Voice is currently deep into the 17th season and the coaches took a little break from the competition to hangout with fellow Voice coach Kelly Clarkson on her show "The Kelly Clarkson Show". The group had nothing but laughs but that didn't mean their competitive streak in "Guess That Famous Voice, Famous Voice Coaches". Everyone was super competitive but no was more competitive than Kelly. But only one person could ultimately guess one particular famous voice correctly and that was Gwen who guess boyfriend and fellow Voice coach Blake Shelton correctly!
