VIDEO : Blake Shelton & Gwen Stefani Get Cozy in Nashville Restaurant

Blake Shelton and Gwen Stefani, who have been dating since at least November, were spotted cuddled up next to each other while sitting at a booth at a branch of O'Charley's Restaurant and Bar in Nashville on Friday night. The country star and his fellow singer and The Voice co-star had also flown to Nashville just before Christmas, to attend a private engagement party for singer RaeLynn. They have reportedly traveled together over the past month, visiting his family and shopping in his home state of Oklahoma, watching an NFL game in Arizona, going on a wine-tasting tour in Santa Barbara, California and frequenting two of her favorite restaurants, with her parents and brother, in her hometown of Anaheim, near Disneyland.
