Blake Shelton and Gwen Stefani have been inseparable since "The Voice" wrapped up last year.

The two are believed to have spent the holidays together. They have been spotted in each other's hometowns. And over the weekend, the pair was in Nashville, Tennessee to attend the wedding of Shelton's stylist, Amanda Craig, at The Loveless Barn on Saturday, Jan. 9.

According to E!, Shelton served as one of the groomsmen while the No Doubt frontwoman attended as her boyfriend's guest.

For the ceremony, the 46-year-old wore a black mesh gown while the country star looked dapper in a black suit.

The website reports that Kelly Clarkson and former "The Voice" contestant RaeLynn were also at the wedding.

The day after the wedding, the Daily Mail posted pictures of the pair after the wedding. The website speculates that Stefani must have caught the bridal bouquet as the "Used to Love You" singer was photographed holding a bouquet of roses while sipping coffee and waiting for Shelton to pack up their car. The couple looked happy as they smiled while preparing for their trip.

Last month, Shelton and Stefani were also in Nashville to celebrate RaeLynn's engagement to Josh Davis. RaeLynn took to her Instagram account to post pictures of the "The Voice" coaches dressed in Christmas sweaters as they posed alongside the newly engaged couple.

The night before the wedding, the two were seen getting cozy at O'Charley's restaurant in Nashville and fans took to social media to express their delight about seeing the celebrity couple.

A source told E! that they were alone and were "all over each other."

"They were there over an hour," said the insider. "No one bothered them. They sat in the back corner by the bar."

The two began dating in October and their relationship was confirmed by Stefani's rep a month later.
