Over the last 24 hrs I have gone through lots of emotions. Fear, Anger, Heartache, Compassion and many others. I truely dont understand why a person would want to take the life of another. Something has changed in this country and in this world lately that is scary to see. This world is becoming the kind of place i am afraid to raise my children in. At the end of the day we arent Democrats or Republicans, Whites or Blacks, Men or Women. We are all humans and we are all Americans and its time to start acting like it and stand together as ONE! That is the only way we will ever get this Country to be better than it has ever been, but we have a long way to go and we have to start now. My heart aches for the Victims and their families of this Senseless act. I am so sorry for the hurt and pain everyone is feeling right now and there are no words i can say to to take that pain away. Just know u all are in my heart and my prayers as we all go through this together. Time to come together and stop the hate! #stopthehate #prayforlasvegas

Aldean also opens up about his fear for America. “Something has changed in this country and in this world lately that is scary to see,” he said. “This world is becoming the kind of place I am afraid to raise my children in.”

“Just know you all are in my heart and my prayers as we all go through this together,” Aldean concludes. “Time to come together and stop the hate!”

Aldean had been scheduled to perform this weekend, but under the circumstances has announced the cancellation of his upcoming shows.

“As a result of what happened in Las Vegas this week, we have decided to cancel this coming weekend’s shows,” said the singer in a statement. “I feel like out of respect for the victims, their families and our fans, it is the right thing to do. It has been an emotional time for everyone involved this week, so we plan to take some time to mourn the ones we have lost and be close with our family and friends.”

The statement continued: “Our plan is to resume the tour the following week in Tulsa, Oklahoma. Our first time back onstage will be a very tough and emotional thing for us, but we will all get through it together and honour the people we lost by doing the only thing we know how to do – play our songs for them. I hope everyone understands why we can’t play this weekend and I’m sorry if anyone is disappointed.”

Aldean concluded: “I want to say thank you for the outpouring of love from my friends and fans we have received over the last couple days. You guys have no idea how much you have helped get us through this tough time. Thank you and God bless.”

His wife, Brittany Aldean, shared her own message in the aftermath of the shooting. “Took me a while to be able to write these words,” she captioned her post on Thursday. “Thank you to everyone who has reached out to Jason and I.”
