Fans at Miranda Lambert’s Oklahoma City concert got a rare treat last Friday, as the country star invited her husband Blake Shelton onstage for an impromptu acoustic duet.

"I don't usually do two acoustic songs in the middle of my set, but I think I should tonight — because I brought my husband with me," Lambert told the crowd, before sitting down with Shelton to sing his hit song "God Gave Me You."
