Fern / Splash NewsGwen Stefani and boyfriend Blake Shelton are enjoying some prime family bonding time before the holidays.
The two and ex-husband Gavin Rossdale's three sons—Kingston, 10, Zuma, 8, and Apollo, 2, took a road trip to the mountains and were spotted walking in Lake Arrowhead, California, located in the San Bernardino Mountains about two hours northeast of Los Angeles. Shelton was also seen drinking a beverage. The group later dined in a restaurant, E! News has learned.
Shelton wore a jacket with a camo-like print and Kingston and Zumo sported T-shirts with the same design.
The singer paired his look with a blue button-down shirt, blue jeans, a two-toned blue cap and tan boots. Stefani wore a California Republic state cap, a gold puffy coat, blue jeans and red boots.
Shelton has often spent time with Stefani's sons since the two went public with their relationship a year ago.
The two singers and stars of The Voice spent Thanksgiving together for the first time last month and made it a full family affair; they also celebrated the holiday with his mother and her parents.
They had met each other's parents at their homes before—her mom and dad live in California, while his mother lives in his home state of Oklahoma.
"It's been just an eye opener to be with someone like her," Shelton said about Stefani on The Ellen DeGeneres Show earlier this month.
"I mean, you think Gwen Stefani and No Doubt, and she is literally maybe the most normal person that I've ever met in my life," he said. "It's been good for me to be with somebody that's so grounded and just a good human being with a great heart."
