A week after Gwen Stefani and Blake Shelton performed their new song, "Go Ahead and Break My Heart," together live for the world to see on The Voice,  Gwen can't hold her excitement, she's over the moon, "That feels extreme. Yeah...It feels like, 'wow, that happened. I can't believe I wrote a song with that guy." "And then we got a chance to sing it together on The Voice," she continued "Like...and everyone got to see that. It was a miracle. It was incredible."
