Blake Shelton is a proud husband to Gwen Stefani.

On Tuesday, Stefani surprised country fans when she joined the 45-year-old country star onstage at night one of CMA's Summer Jam event in Nashville, Tennessee. The couple, who tied the knot earlier this month, performed their duet "Happy Anywhere" for the sold-out crowd at Ascend Amphitheater.

Shelton took a pause mid-performance to introduce his wife "Gwen Stefani Shelton" as the crowd started to clap and cheer them on.

Shelton, who wore a black button-up shirt and jeans, and Stefani, who looked stunning in a white dress and matching cowboy boots, then continued singing while looking adoringly at each other.

Fans caught the moment on video and shared it on Twitter.

Twitter users couldn't help but gush over the sweet moment.

"They're so dang cute together! I wish them nothing but the best and a long, happy marriage. They both deserve it," one commented, while another fan wrote, "Thank you sooo much what a great atmosphere and singalongs feel like I would be there."

"What a beautiful couple. God bless you both forever. Keep the love shining," a third person commented. "True love always comes together in the right timing! Meant for each other," wrote another.

"Thank you so much for sharing! I can't get enough!" another fan commented.

After the performance, Stefani shared on Instagram a photo of her white dress, writing "@blakeshelton next time i get to wear a pretty dress will u take a picture with me? gx #picturetakerhater." She also posted on her Instagram Story videos of herself with her 7-year-old son Apollo.

The singer also showed her husband some love on Twitter after a fan shared photos of Shelton at the performance and wrote, "Apparently Blake Shelton spent his honeymoon getting hotter. Stefani replied, "that's right gx."

Stefania and Shelton tied the knot in a backyard chapel on his ranch in Tishomingo, Oklahoma, on July 3. Forty of their close friends and family members were there to witness the event, including fellow "Voice" star Carson Daly, who officiated the ceremony.

Shelton and Stefani skipped the traditional honeymoon as they are both busy with their respective careers, People reported. They immediately returned to Los Angeles after their wedding.
