But how do the newcomers feel about appearing on the hit NBC show with their real-life friends?
"I love The Voice and I've had the most fun watching it," Grammy award winner Sheryl says. "The fact that when they do the initial audition they have no idea what you look like -- which kind of like in the old days before videos, we didn't really know what Foreigner and Kansas and all these bands looked like -- so it's kind of great. You just get to hear someone sing and judge them on the passion and the emotion that you're hearing."
And is Blake as goofy in real-life-as he is on the show?
"I love working with Blake -- I've known Blake for a long time, I actually have known Miranda for a little while -- and he is hilarious," Sheryl confirms. "Who he is on the show is exactly who he is in real-life, and also he knows a lot about music so that makes it fun. I'm just having a ball with him."
