The lucky fans who attended Miranda Lambert's concert in Dayton, Ohio last week got a big surprise when Miranda's husband Blake Shelton showed up on stage with his acoustic guitar and performed his latest single 'Sure Be Cool If You Did' as a duet with his wife.

These two are the Brad Pitt and Angelina Jolie of country music, they are the epitome of America's sweethearts. After hearing them sing this song together I think Blake should have recorded it that way for the album, they are mesmerizing together, check it out!
