Fans lucky enough to attend the Dayton, Ohio stop of the Miranda Lambert/Dierks Bentley Locked and Reloaded tour last night (Feb. 15) got a real treat. That's because Blake Shelton showed up to perform his brand new single 'Sure Be Cool if You Did' with his wife Lambert.

When Shelton made his way to the stage, the audience erupted into defeaning cheers. With his acoustic guitar in hand, Shelton took a seat next to his beautiful, leather jacket-clad wife and they performed his brand new song as thought it were meant to be a duet.

Lambert was gazing lovingly at her husband as she added a beautiful layer of harmony to the new song. She rocked back and forth as she sang with him. They exchanged plenty of glowing glances at each other while performing. It was truly a crowd pleasing moment, one that made the show extra special for attendees.

Shelton and Lambert are easily one of the cutest country couples ever. They work and play with equal fervor!

Shelton revealed earlier this week that he will release 'Based on a True Story…' on March 26, which is the day after Season 4 of 'The Voice' premieres so he has a busy couple of months coming up. It was wonderful to see him get some live time in with his wife. It's moments like this that remind us why they are so perfect for one another.
