Blake Shelton fans had a special treat Thursday night in Florida, as the singer’s wife Gwen Stefani joined him on stage for a performance. Stefani stepped on stage with Shelton wearing a fluffy purple jacket and equally furry black boots. Underneath the jacket was a T-shirt that read, “I [Heart] Cowboys.” The couple proceeded to sing their duet “Nobody But You” together. After the performance, the two embraced as Shelton kissed Stefani on the cheek. When they pulled apart, Shelton told the audience, “I’m sorry, I forgot y’all were here.” “Gwen Stefani, everybody!” he continued, before correcting himself. “Did I say Gwen Stefani? I meant Gwen Shelton. I’m sorry, I’m sorry.” Who are some of your favorite celebrity couples?
