The couple and Stefani's three children, Kingston, 10, Zuma, 8, and Apollo, 2, enjoyed a trip to the mountains and spent the day walking around Lake Arrowhead, Calif., located in the San Bernardino Mountains. Shelton was seen drinking a beverage and later the group dined at a restaurant, E! News reports.
Shelton wore a printed jacket with a blue button-down shirt, blue jeans, a baseball cap and tan boots. He seems to be rubbing off on Stefani's sons because they were dressed in similar attire.
Stefani kept it casual wearing a gold puffy coat, California Republic state cap, blue jeans and red boots.
Shelton is often seen spending time with Stefani's sons since the two publicly announced their relationship a year ago.
