The 39-year-old country star and his fellow singer and The Voice co-star, 46, 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. Instagram user @rppofficial posted a photo of the two.
They were alone and "all over each other," a source told E! News exclusively.
"They were there over an hour," the source said. "No one bothered them. They sat in the back corner by the bar."
