'The Voice's' Team Blake: Does Dia Frampton or Xenia have your vote?

We have to admit that when "The Voice" began, we weren't sure Blake Shelton would venture far out of his country-fried comfort zone, but he surprised us by supporting Dia Frampton and Xenia all the way -- and they've emerged as two strong artists in their own right.

On Tuesday's semi-final found, Dia performed a version of "Losing My Religion" by R.E.M. "I'm feeling a lot more comfortable," she said. "I think with 'Heartless' I did kind of let go."

She even stepped out from behind her piano. "If you want to play the guitar, rock it," Shelton told her. "This girl isn't just someone who can sing, this girl is someone who has a vision."

Her performance wowed the coaches, and we're guessing it'll be a big seller on iTunes. "What's so interesting about you is that in the beginning I'm all like '[she's] cuddly, soft'," said Christina Aguilera, "but I've seen you grow so much on the show. You kind of made this an interesting game."

Shelton added, "This show just did what it was supposed to do. A girl just stood out there and left her heart and soul laying there on the stage. Gosh dang it; I'm glad to know you."

His girl Xenia performed "Man Who Can't Be Moved" by The Script, one of her favorite bands, switching the lyrics to "one who can't be moved" to avoid a gender-bender. "This is your chance to think about being the voice of your generation," Shelton told her. "You can change the sound of what's popular."

After the performance, Adam Levine was impressed. "The song was a little sleepy, but you sound great," he says.

"I enjoy to watch you be so unaffected by all of this. You're so cool. It's quaint. You gracefully perform these songs under so much pressure," added Cee-Lo.

"We're all thinking the same thing, because it's so obvious," Shelton says. "One day, when I'm done with this show and I'm back in Oklahoma driving my truck, I know I'm going to hear Xenia's voice on the radio... I'm glad that I knew you when."
