Gwen Stefani and Blake Shelton made their CMT Awards red carpet debut as a couple! Although the pair aren't strangers to walking side by side on a carpet, Sunday marks a milestone for the duo, as it is their first time attending this particular show together. Stefani, 53, dazzled in a sparkling skirt paired with a white button-down shirt and tie with black fringed boots. Shelton, 46, cleaned up nicely, dressed in his signature denim and switching out the plaid for a suit jacket and tie.It's a sweet date night for the duo as Shelton has been away from home for his Back to the Honky Tonk Tour along with supporting acts Carly Pearce and Jackson Dean. «It's terrible,» the singer previously told ET of being away from home.
