Shelton also shared his own throwback wedding photo in honor of Valentine's Day. The "God's Country" singer posted a black and white photo of the two standing at the altar. "I'm the luckiest man alive," he wrote alongside the Instagram snap. "Happy Valentine's Day, @gwenstefani! I love you!" The couple, who first met on the set of The Voice in 2015, are celebrating their first Valentine's Day together as husband and wife after tying the knot in July at Shelton's Oklahoma ranch. Last year, Shelton surprised Stefani with a floral bouquet, and she shared a tribute post for her then-fiancé to commemorate the occasion. "Happy Valentines!! Thank u @blakeshelton for loving me," she wrote on her Instagram Story. Gwen Stefani Instagram Blake Shelton Shares Sweet Performance Video Dedicated to Wife Gwen Stefani: 'Couple Goals' At their wedding, Shelton wrote "We Can Reach the Stars" for Stefani to use as his vows, and later said he was "really proud" of the track. "I'm really proud of 'We Can Reach the Stars' and I'm really honored to be with her," Shelton said in a statement. "That's why we got married in the first place. That's why we wear rings… because we want everyone to know. I'm thrilled to share this song with the world." In November, a source told PEOPLE that the pair are thriving in married life. "Gwen and Blake are doing well. They act like newlyweds," the source said. "They have the best chemistry." Since getting together, the singers have often given fans intimate glimpses into their life together, including in December, when they celebrated their first married Christmas by trying to make an Italian timpano pasta dome — something they'd tried and failed to make in the past, but succeeded in this year.
