As anyone who's ever visited Nashville can attest, Music City is a town full of surprises. That's what one Twitter user discovered recently, when her sister apparently ran into none other than pop star Ed Sheeran hanging out with Kelsea Ballerini and Morgan Evans at a local bar.

That's not all, though. The stars weren't just hanging out, they were indulging in a little karaoke action as well. Watch above to see their take on the Backstreet Boys' 1999 classic "I Want it That Way." (We love how Sheeran and Ballerini are sharing a mic, and how Ballerini has her arm around his shoulders, all buddy-buddy!)

Evans, as well as wife Ballerini, was doubtless in a party-ready mood that evening, as his new album, The Things That We Drink To, was set to drop the next day (Oct. 12). The record is filled with moments of celebration much like the one in the bar with Sheeran...as well as a variety of other emotions.

"When the track listing for the album was coming together, I realized that songs were finding their place as there were these moments, whether it was drinking to someone you've lost or drinking to meeting the girl or finding a new home in America," the Australian singer explained to Taste of Country. "They're all these moments you can raise a glass to."
