“Had the best thanksgiving,” Stefani captioned an Instagram photo of her 41-year-old boyfriend giving her a kiss on the cheek.
She also posed for her a family portrait and shared a picture of PEOPLE’s Sexiest Man Alive fishing with his arm around her youngest son, 3-year-old Apollo.
Stefani also gave followers the behind-the-scenes scoop on her Instagram story, sharing videos and photos of the decorations, including incredible centerpieces on the Thanksgiving dinner table.
The singer recruited her sons, nieces and nephews to make place settings with each guest’s name, and recorded son Zuma placing Shelton’s name at a seat next to hers.
Shelton even made an appearance on camera, announcing You Make It Feel Like Christmas had moved up on the iTunes Charts as the room burst into cheers. His phone as showed that he had purchased the album, which features a duet between the couple.
Stefani introduced fans to her family members as they prepared in the kitchen (or enjoyed a glass of wine with her).
She also showed her sons hanging out on the holiday and heading to the park before dinner.
On Friday, Stefani flew back to Los Angeles so she could attend her holiday pop-up store at The Grove, then returned to Oklahoma for the weekend.
Stefani and Shelton began dating in November 2015 when they met as coaches on The Voice, not long after Shelton’s divorce from fellow country crooner Miranda Lambert and Stefani’s divorce from husband Gavin Rossdale.
And for their first Christmas together in 2015, they vacationed at Shelton’s home in Tishomingo, Oklahoma, dressed in matching camouflage outfits.

“[He’s] somebody that is at the top of their game and talented and genuine and cool and generous and just not self-aware at all — completely a man,” Stefani told PEOPLE of why her boyfriend is the perfect choice for Sexiest Man Alive.
“He doesn’t even know how cute he is. [He]’s cocky but only because he’s a cowboy!” Stefani joked.
“It’s interesting because I don’t think any of those things like beauty or sexy or whatever way you want to describe humans is necessarily a physical thing that people are attracted to,” she said. “It’s all about the heart, and [Blake] has that big ol’ gigantic heart in there, so he’s quite an attractive human. I’m not the only one that thinks it!”
