More than 400 people were injured and 50 were killed after suspected shooter Stephen Paddock opened fire from the nearby Mandalay Bay Resort and Casino during the final night of the Route 91 Harvest Music Festival in Vegas. Police said Monday morning that Paddock took his own life after orchestrating the shooting.

Aldean, who was performing at the time of the shooting, spoke out earlier this morning, followed by his wife Brittany, who is expecting their first child later this year.

"Tonight has been beyond horrific. 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," the 40-year-old Grammy nominee wrote.

His wife Brittany, 29, added later in the morning that "we are safe."

"Our angels were definitely watching over us tonight. No words for what happened... Just horrific. Praying for everyone," she wrote.

The Aldeans just celebrated their baby shower earlier this weekend, though it's not clear if it was in Vegas. The duo posted pictures of the shower on social media.

Jake Owen, Lee Brice and Chris Young, who also performed at the concert, responded to the shooting on Twitter.

On Monday Owen called into "Good Morning America" to describe what he witnessed. "[You're] standing there, you could hear the bullets starting to hit the roof of the stage and people started fleeing everywhere. You could hear people screaming."

He continued, "I keep saying it was like a bad movie that you’ve seen before but never thought it would be real life."

Young shared similar sentiments.
