Engaged duo Blake Shelton and Miranda Lambert are returning to the "river" for a new duet. The couple, who previously sang the rockin' tune 'Draggin' the River' together, reportedly recorded a new song called 'Red River Blue' last week. Songwriters Buddy Owens and Ray Stephenson both posted ecstatic Facebook updates about the couple using their song, which Stephenson had previously recorded.

Owens wrote the following update: "Thanks to Blake Shelton and Miranda Lambert for recording my song 'Red River Blue' today! Also, thanks to my good buddy and co-writer, Ray Stephenson!"

Stephenson similarly posted, writing: "Good news to share! Blake Shelton and Miranda Lambert just recorded a song Buddy Owens and I wrote called 'Red River Blue.' Blake says the song sounds great and it's 'really special.'"

The song will most likely appear on Shelton's new album, due out on July 12. By that time, he and Lambert should be husband and wife, as the duo's set to wed this month. If you'd like to check out Shelton and Lambert singing on their 2010 duet 'Draggin' the River,' you can listen to it here.
