Shelton and Stefani attended the wedding of Shelton's friend and hairstylist Amanda Craig. Craig married Joel Borski in Nashville, Tenn. last week, and Shelton and Stefani posed for fun photo booth pictures that the bride posted to Instagram on Sunday.
In the photos, Shelton and Stefani can be seen cozying up to each other as they smile for the camera. Stefani wore a black mesh dress to the wedding, while Shelton matched the "Used to Love You" singer in a black suit.
Shelton and Stefani confirmed their relationship to ABC News last November.
Shelton, 39, and his wife of four years, fellow country singer Miranda Lambert, announced they were divorcing in July of 2015, and Stefani, 46, split from her husband of 13 years, singer Gavin Rossdale last August.
