Heartbroken, Jason Aldean took to Instagram after the horrific shooting in Las Vegas to encourage his fans to "stop the hate." 

"Tonight has been beyond horrific," he said in a caption with a photo of the city. The shooting, which killed at least 59 and injured 527 during the Route 91 Harvest country music festival, started as Aldean began his final show in Las Vegas on Sunday night.

Jake Owen, who performed before Aldean, spoke to FOX & Friends about how it all felt like a "bad movie."

Jake Owen Described Horrific Las Vegas Shooting  “Gun shots were ringing off of the stage rigging and road cases,” Jake Owen tweeted. “No one knew where to go..thank you LVPD and responders for keeping us safe.”

"When the shots started being fired, at first I thought it was pyrotechnics," Owen told FOX & Friends. "People were running in all directions."

He said he believes it's a "miracle more people were not injured. ... It was a perfect angle. You have a sea full of people out there and a guy that sounded like a fully automatic rifle. There was no chance for a lot of people to get out of the way."

At least 59 people were killed and 527 were injured when 64-year-old Stephen Paddock fired a barrage of gunshots from the 32nd floor of the Mandalay Bay Resort and Casino on Sunday night.
