'The Voice': The Blake & Gwen Moment Everyone's Talking About

Blake Shelton and Gwen Stefani are going strong!

ExtraTV.com was inside “The Voice” tonight when Blake took everyone by surprise with a blush-worthy comment about Gwen.

It happened just after Amy Vachal from Adam Levine's team finished singing Drake's “Hotline Bling.” Blake started with, "I don't think there's ever been a more elegant and classy performance of a song about a booty call in the history of music. I mean, that was unbelievable. I hear that song on the radio every day.” When Adam seemed surprised that Blake knew the song, Blake responded, "Gwen sang it to me on 'The Tonight Show.'” This caught everyone by surprise. It seemed to make Gwen blush and fluster Carson Daly a little. Watch the moment here!

Afterward, during the commercial break, we saw Blake run over to Gwen's chair with a sheepish grin on his face, as the couple talked it out.

Another moment fans didn't see was at the beginning of the night. Before the show started, each of the coaches took the stage. Gwen arrived last and immediately walked up to Blake and gave him a huge hug. As they embraced, he spun her around. It was very romantic.

On nearly every commercial break Blake walked over to chat with Gwen (as seen in the top photo), and on one occasion they even briefly left the building. At the end of the show Adam and Gwen were seen chatting up Blake in his big red chair.

Before the show, "Extra's" Renee Bargh caught up with Blake and Pharrell Williams on the red carpet, where Shelton dished on his rumored country song with Gwen.
