The country singer couldn't hide his affection for girlfriend Gwen Stefani during former Voice contestant RaeLynn's wedding on Saturday in Franklin, Tennessee.
In photos from the nuptials, Shelton, 39, can be seen holding onto Stefani's hand as they greeted and hugged RaeLynn, who was on Shelton's team during the reality competition's second season.
While watching the beautiful bride, 21, walk down the aisle, Shelton put his arm around the "Make Me Like You" singer's shoulders, cuddling up amid chilly temperatures. He also planted a sweet kiss on her head during the outdoor ceremony.
Stefani, 46, wore black fishnet tights with her short-sleeve, fit-and-flare black dress, for the wedding. She covered up in a black cape jacket, and wore her hair in a high ponytail with pompadour.
Raelynn shared a photo of the couple on Instagram on Sunday, writing, "What a beautiful day with such beautiful people. I am so thankful for everyone in my life and for my amazing Husband."

RaeLynn wed financial advisor Josh Davis after getting engaged last October. Davis led RaeLynn on a scavenger hunt around Belmont University in Nashville, Tennessee, taking the country singer to various places of meaning before popping the question.
Shelton and Stefani, who is also a coach on The Voice, have been dating since last fall. The pair are already regulars on the wedding circuit – in January, Stefani even caught the bouquet at Shelton's hairstylist's nuptials.
