When Charles Kelley, Dave Haywood and Hillary Scott -- who make up the mega-talented country music trio Lady Antebellum -- say that they love their fans, they really mean it. In fact, when Lady A superfan Jessica Stokes appeared on 'Anderson' on Tuesday, she couldn't stop talking about how much she loves the group and how she's never seen them in concert -- that's when the trio gave her the surprise of a lifetime.

Basically, Stokes sat down with host Anderson Cooper under a cleverly disguised ruse. She thought she was on the new daytime talk show to simply chat about her fandom and to try and win Lady A tickets by passing a quiz about the band. Stokes told Cooper that since her husband is in the military and her family has been stationed in Germany for a few years, she hasn't had much opportunity to see a live Lady Antebellum show, and when she did, she missed it.

The wife and mother shared the sad story of when she and her husband actually scored tickets to see the 'We Owned the Night' hitmakers play in London, but were then unable to board their flight in time to make the concert and spent the length of the show in the terminal.

As a military wife who doesn't always get to see her husband often, Jessica talked about how the Lady A hit 'I Run to You' really hits home with her. "That song makes me think about him… and there are so many songs that remind me of our relationship," she said.

When Cooper tested Stokes' knowledge about Lady Antebellum, she answered the first two questions correctly with absolutely no hesitation. Then came the third question: "What song is this?" Cooper asked, as a truly live version of 'Need You Now' started playing in the background. Stokes had no idea that all three members of the group were there, miced up and singing the tune backstage.

The second the trio walked out singing, the world's biggest Lady Antebellum fan jumped out of her seat screaming. "Shut up!" she yelled in disbelief (at least a dozen times).

Stokes will get to see a full live show soon, but we have a feeling that hugging her three favorite country stars more than makes up for that missed show in London. Lady Antebellum sure know how to treat their fans right!
