Jason Aldean and Luke Bryan made history on Saturday night when they packed 60,000 screaming fans into the University of Georgia's Sanford Stadium for the stadium's very first concert as part of Jason's Night Train Tour.  

Fans then got a huge surprise when Jason welcomed rapper Ludacris to the stage during Dirt Road Anthem. This wasn't the first time Ludacris surprised Jason's fans, the pair performed the song together back in 2011 at the CMT Music Awards. 

"This is definitely one of the highlights of my career, playing here tonight," Jason told the crowd (via USA Today).

Also making an appearance at last night's show was Kelly Clarkson who joined Jason during Don't You Wanna Stay, although her appearance was prerecorded and played on the huge high-definition video screens.
