Lady Antebellum stopped by 'Ellen' on Friday to perform their big hit 'Just a Kiss,' but while they were there, the trio disguised themselves as waiters in order to surprise some of their biggest fans, who were dining in a restaurant.

On the 'Ellen' set, Hillary Scott sang her 'Just a Kiss' lines dressed down from her usual night makeup and shimmer, looking pretty in a pink top with her hair literally let down. The band was backlit by sunset colors -- purple, pink, orange and blue -- which really set the mood as Dave Haywood accompanied Scott and Charles Kelley on the keys.

Following their performance, however, Ellen DeGeneres decided to have a little fun with the most popular group in country music. Two of the 'Need You Now' band's biggest fans were dining in nearby a restaurant, not suspecting anything -- not even their super suspicious waitstaff. Scott, Kelley and Haywood took turns waiting on the couple, starting with "the least recognizable member of the band" (his words) Haywood, who took them their bread. Just seconds later, Scott brought out their drinks, though the pair seemed unfazed by her presence. Thankfully, the third time was a charm. When Kelley came out to serve the couple a romantic dessert, cake lit with candles, the woman's face lit up, instantly recognizing her favorite male lead.

The trio sang an a capella version of their Grammy-winning hit 'Need You Now,' and even delivered a bouquet of roses to their biggest fans. Before leaving the show, DeGeneres gifted the group by making sure all members of Lady A were fully stocked with 'Ellen' underwear so they would never be without on tour.
