Blake Shelton and Gwen Stefani heated up the Billboard Music Awards' stage when they performed a rendition of their duet "Go Ahead and Break My Heart."
The country singer admitted that the two shared a few laughs in between making our hearts melt.
"We kind of did laugh a few times," he said on today's "The Ellen DeGeneres Show." "There's moments where it's like, wow we're singing this song like we're going to break up, and we're not breaking up right now so it seems kind of weird."
How Blake Shelton and Gwen Stefani Began Their Relationship Gwen Stefani Releases New Single About Blake Shelton Blake Shelton on His 'Fast' Divorce With Miranda LambertShelton also admitted that he began writing the song before taking his relationship with Stefani seriously.
After all, he had just divorced fellow country singer Miranda Lambert after four years of marriage, and the No Doubt front woman had just ended her 13-year marriage with Gavin Rossdale.
"When we wrote the song, we never saw it going there. I don't know that we ever really saw it going anywhere," he explained. "I only started the song to impress her; to be like, 'Hey, I’m writing a song about you.'"
"And so I sent it to her, and then she wrote the other half of the song. I was like, 'Oh, she just one upped me,'" he deadpanned.
Stefani, 46, and Shelton, 39, began dating publicly last November.
