Jason Aldean's got fans in high places: During the country superstar's set at the 2017 iHeartCountry Festival on Saturday night (May 6), fellow star Dierks Bentley could be spotted sidestage, taking in Aldean's show.

iHeartRadio shared a video of Bentley, watching Aldean from the edge of the stage. As Aldean is performing his hit "A Little More Summertime," Bentley can be seen filming his performance on his phone.

Aldean and Bentley's relationship goes back at least a decade: In 2007, Aldean -- then still a rising star -- opened for Bentley and Miranda Lambert during the Free and Easy Tour. At that time, Aldean had recently released his sophomore album, Relentless; two years prior, in 2005, "Why" had become his first No. 1 single.

In addition to Aldean and Bentley, a number of other country heavy hitters were in Austin, Texas, on Saturday night for the 2017 iHeartCountry Festival, which took place at the Frank Erwin Center. Little Big Town, Brantley Gilbert, Rascal Flatts, Old Dominion, Jake Owen, Darius Rucker, Lady Antebellum and Kelsea Ballerini, among others, also performed during the event.
