Gwen Stefani and Blake Shelton are quite the jetsetters as of late.

The two were getting cozy in the corner of O'Charley's restaurant in Nashville, Tennessee, on Friday, a source tells ET.

According to the source, the lovebirds arrived around 9:45 p.m. by a black SUV that Shelton was driving. The country crooner and his rocker girlfriend took a seat next to each other at a booth, and were "all over each other."

"They were very touchy feely," the source says, adding, "You could tell Blake was glad she was right there by his side."

The source also revealed that no one bothered the two as they sipped on drinks.

The No Doubt frontwoman and the "Boys 'Round Here" singer are back in town for a wedding, as Shelton's stylist, Amanda Craig, got married on Saturday. The bride is a celebrity stylist and co-owner of the Nashville salon, Leigh, Edwards & Company.

The wedding was a star-studded affair with Reba McEntire, Kelly Clarkson, Carson Daly and Dave Haywood of Lady Antebellum all in attendance. Shelton's former Voice contestant, RaeLynn, was also at the wedding, and took to Instagram to share a snap of the two ahead of the ceremony.

"Tradition nose picking pic," she captioned the black-and-white photo.

Shelton and Stefani were both in Nashville last month to celebrate RaeLynn's engagement to her fiancé, Josh Davis, with an ugly-sweater party planned by Craig and Shelton.

It wasn't their only trip in December, however, as they also traveled to Anaheim, California -- Stefani's hometown -- after the two spent Christmas together in Blake's home state of Oklahoma. They also were spotted at an Arizona Cardinals game in Glendale, Arizona, and a wine tasting adventure in Buellton, California, over the holidays.

Stefani, 46, and Shelton, 39, haven't been shy with their PDA since confirming their status as a couple in November. The two got together after the No Doubt frontwoman announced her divorce from Gavin Rossdale in August, just one month after Shelton and Miranda Lambert called off their marriage.

Earlier this week, the two took their love to Twitter, exchanging a series of flirty messages. Watch the video below to hear more.
