The 41-year-old country star treated Stefani and her three sons, 11-year-old Kingston, 8-year-old Zuma and 3-year-old Apollo, to the scenic ride after visiting the Chicksaw Cultural Center in Sulphur, Okla.
Stefani shared a series of videos on Snapchat from the chopper, including a clip of herself, Kingston and Apollo preparing to take off. Apollo dozed off for a nap shortly after the helicopter took flight.
"Had an incredible time today at the Chicksaw Cultural Center!! Can't believe I hadn't seen it before! @ChicksawCCC," Shelton tweeted.
Stefani and Shelton confirmed their relationship in November following their respective splits from Gavin Rossdale and Miranda Lambert. Shelton told Jimmy Kimmel Live! the next month that he and Stefani enjoy Bachelor-style dates in his private helicopter.
"Yes, I have a helicopter," the country star told host Jimmy Kimmel. "[Gwen and I] do [go up on dates]. We use that thing a lot. It gets a lot more use than you would think."
"I don't fly it," he qualified. "I don't know how to fly, so we use somebody else."
Shelton and Stefani, who shares her sons with Rossdale, took the boys on a fishing trip Sunday, and returned to the water Tuesday. The country star hails from Ada, Okla., and owns a ranch in nearby Tishomingo.
