Stefani shared a few glimpses of their weekend at Shelton's ranch in Tishomingo, Oklahoma, on Snapchat Sunday, which included a boat ride on the lake with her sons, Kingston, 10, Zuma, 8, and Apollo, 2.\
The photos (below) show Shelton, 40, getting some assistance captaining the boat from Apollo, who sits comfortably on the country crooner's lap at the helm. Stefani, 46, can be seen smiling in the foreground of the snap wearing a leopard print swimsuit while her other two sons horse around at the back of the boat.
On Monday the "Used to Love You" singer took to Instagram with yet another moment from their vacation, this one of her and Shelton relaxing on a coach wearing matching Hawaiian shirts. Stefani captioned the 'gram simply, "Hi Gx."
This isn't the first time Shelton has let Apollo handle heavy machinery on his ranch. In August Stefani snapped a photo of the little guy behind the wheel of a gigantic tractor!
