Jason Aldean, Brad Paisley and More Celebs React to Mass Shooting in Las Vegas

Country music star Jason Aldean, who was onstage as bullets started raining down on the Route 91 festival on Sunday night, was one of many celebrities who expressed shock, horror and sympathy as authorities were still counting the dead on Monday.

"Tonight has been beyond horrific," the singer wrote on Instagram. "I still don't know what to say but wanted to let everyone know that me and my crew are safe. My thoughts and prayers go out to everyone involved tonight. It hurts my heart that this would happen to anyone who was just coming out to enjoy what should have been a fun night."

Singer Ariana Grande, who was performing in Manchester when a bombing killed 22 concertgoers last May, called for increased gun control in a powerful tweet.

"My heart is breaking for Las Vegas," she wrote. "We need love, unity, peace, gun control & for people to look at this & call this what it is = terrorism."
