Jason Aldean has Luke Bryan's back. While the 'That's My Kind of Night' singer himself hasn't responded publicly to comments made by Zac Brown about his song, Aldean had some strong words for people "runnin' their mouths."

Aldean took to Instagram to voice his opinion on the hot story. "I hear some other artist are bashing my boy Luke Bryan's new song, sayin' it's the worst song they have ever heard," he writes. "To those people runnin' their mouths, trust me when I tell you that nobody gives a s--- what you think. It's a big ol' hit, so apparently the fans love it which is what matters. Keep doin' your thing LB!!!"

Earlier this week, news broke about what Brown told Vancouver radio station JRFM. “I love Luke Bryan and he’s had some great songs, but this new song is the worst song I’ve ever heard,” the 'Chicken Fried' hitmaker said. “I know Luke, he’s a friend. ‘[That's] My Kinda Night’ is one of the worst songs I’ve ever heard."

Brown also took a shot at "tailgate in the moonlight, daisy duke songs." “When songs make me wanna throw up, it makes me ashamed to even be in the same genre as those songs,” he added.

Aldean, Bryan and Brown are all from Georgia. Brown did reiterate on Twitter that he is a fan of Bryan -- just not that particular song.
