One shot, which you can see below, shows the pair of nearly two years stealing celebration kisses for the camera. For the occasion, Stefani sported a braided forehead headband and freshly applied makeup, while Shelton donned his signature ball cap.
Gwen wrote, “I get to kiss on the birthday boy @blakeshelton #happybirthdaycowboy gx.”
In another shot, fans get a glimpse of Shelton’s armadillo-shaped birthday cake. The tall drink of water posed next to the cake creation that was adorned with metallic gold scales. Stefani captioned, “Birthday armadillo @blakeshelton gx #bdayboy #cake.”
Stefani filmed the goofy moment and shared it with fans online. She wrote, “Celebrating the birth of my #bestie #favorite @blakeshelton.”
Following the fun-filled afternoon, Shelton took to Twitter with words of gratitude for his girlfriend and fans. He wrote, “Thanks for all the happy birthday wishes!!! 41 ... (expletive) man I’m beating the odds.”
Of course, Shelton’s birthday wasn’t the only big celebration. June 18 also marked Father’s Day, and Stefani’s dad, Dennis Stefani, was on hand to celebrate with his rock star daughter and the birthday boy.
Shelton spread the love and wrapped his arms around Stefani’s dad and even planted a kiss on his cheek.
