Miranda Lambert was on her way to a Jacksonville, Fla. gig Saturday (June 14) when she decided to make some fans very happy with a quick pit stop. The 'Automatic' singer stopped in Fort Walton Beach and decided to play a surprise show!

She had some time to kill before her Sunday show at EverBank Field so she pulled her little silver camper over and decided to play a free two-hour show. What's the best way to promote a surprise show? Social media, of course.

After the tweet was sent and Lambert's Airstream was seen, fans quickly started to line up at the Florida nightclub, according to CMT. The venue, which has a 700-person capacity, filled up with music loving fans for a two-hour concert.

Lambert, who wore holy jeans and a tank top, a big teal belt buckle and a sparkly headband, played her songs 'Fastest Girl in Town,' 'Heart Like Mine,' 'Even Prettier' and 'Gunpowder and Lead' before doing something a little different. She let band member Carolyn Dawn Johnson take center stage for 'Summer of '69,' which was made popular by Bryan Adams in 1984. They also played a few covers for the packed crowd including Led Zeppelin’s 'Rock and Roll' and the Faces’ 'Stay With Me.'
