Luke Bryan shared his thoughts on the mass shooting in Las Vegas over the weekend during his appearance with his fellow American Idol judges Lionel Richie and Katy Perry on ABC's Good Morning America yesterday (Wednesday, October 4th). He said the news was especially hard to take. “I mean, it was one of the most heartbreaking days of my life and for this country, too. I talked to Jason Aldean very early that morning and hearing one of your best friends shaken up like that, knowing they'll never be able to un-see these things and . . . I don't know. I get a lump. You get lumps and you get nauseated. Katy and I and Lionel, we talked about it. There's just gotta be something we can do from the mental health issue to all of the issues that are causing these things.” in Centralia, MO.
