How would you like to celebrate your 21st birthday at a Luke Bryan concert? How awesome would it be if you got to go up on stage and actually drink a legal beer with Luke?!? That is exactly what happened to one birthday girl at a concert at the YUM! Center in Louisville, KY! 

After Luke pulled her up on stage, he made sure to check (and autograph) her identification and other memorabilia. Then he prompted his road crew to bring out the beers. Before they drank their drink, Luke sang her a goofy version of 'Happy Birthday' and gave her a kiss. What a guy! He also publicly showed his support for the film, 'American Sniper.' The crowd loved that!
