We like Blake Shelton and we love Gwen Stefani but that doesn't mean their music needs to join forces ...

The celeb couple debuted their new duet "Go Ahead And Break My Heart" on last night's episode of their show The Voice -- and while we like them both separately their music styles just don't seem to mesh well together.

For the performance Blake looked like his country boy self and Gwen opted for a glittering look that was in keeping with her new ice-skater glam style.

Shelton said about releasing the song, "We're a little bit nervous about it, but nervous in a way that we can't wait and nervous in a way that we hope people think it's as good as we think it is." The singer added, "It's like people getting a look at something personal for the first time."

He told the mag that the song, which is co-written by the real-life couple, is, "about some serious insecurities that we had when we first started down this road with each other." The 39-year-old crooner admitted, "We both had trust issues. We were getting over it, but we wrote this song about it, and it's perfect."

Well at least they like it!
