Gwen Stefani shared photos on Instagram with her hubby, Blake Shelton, on their first Halloween together. In the snaps, the ‘Hollaback Girl’ singer is wearing a farmer costume alongside the country crooner, sporting a poncho and Wienerschnitzel hat. Gwen writes in the caption, ‘Met you in October, I had nothing to lose. Dressed up like a country girl, I knew you’d approve. Knew I had to kiss you on the Halloween moon.’
