Ahhhhhh we love this so much!

Gwen Stefani and Blake Shelton performed their brand new duet “Go Ahead and Break My Heart” at the 2016 Billboard Music Awards in Las Vegas on Sunday night, and this was easily one of our favorite sets of the night. Just look at the way the two look at each other...swoon!

The song is off of Blake's latest album, If I’m Honest, and the singers and Voice coaches just released it a few weeks ago. "The story is that he had written this song and sent it to me on my phone," Gwen said during a recent appearance on Chelsea Handler’s Netflix series Chelsea. "He's like, 'I wrote this song.' And I was like, 'Whoa, what if I don't like it? Huge turnoff!' I listened to it and thought, Oh, my God, I love this. He said, 'Write the rest of it."
