Brantley Gilbert's wife, Amber, has inspired several of his songs over the years, including a new one, "Stone Cold Sober." He also credits her as the reason he has been guarded with his heart.

"She always had a very, very, very big piece of my heart," Gilbert tells North Carolina radio station WWGP AM 1050. "I think that had a lot to do with why I never could give a lot of myself away."

After several years apart, the singer met up with Amber last June, and single life as he knew it would soon drastically change.

"When she walked around the corner, it wasn’t anything I could do," he recalls. "All that 'single for life' s--t just went out the window."

The happy couple married in June 2015, and Gilbert shares with the station what life is like now, as a married man.

"She's my best friend, too," he gushes. "There's nothing like having somebody that loves every single bit of you, and that you love the same way, to actually, really share it with. Everything that's mine is yours. Every bit of joy in my heart, you know, every smile on my face is yours. It's awesome to be able to share that with somebody."

It sounds like there are plenty more Amber-inspired songs on the way.
