The world is recoiling in horror at Sunday night’s (October 1) shooting at the Route 91 Harvest Festival in Las Vegas.

Jason Aldean was performing when a shooter fired multiple rounds, killing more than 50 people and injuring hundreds more, in what is being called the deadliest mass shooting in U.S. history.

Celebrities from all walks of life have taken to social media to express their sadness at what happened, including Aldean himself, who let everyone know he was okay, but that the incident “hurts my heart.”

Take a look below to see what other had to say.

Tonight has been beyond horrific. I still dont 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. #heartbroken #stopthehate
