If you’ve seen Chris Stapleton perform over the last few years, you’ve probably noticed he tends to look more to stage left than the crowd. And for good reason—that’s where his wife, Morgane, is usually standing as she provides her rich harmonies.

As Chris recently told Kix Brooks of American Country Countdown, with the woman who knows him best by his side, the bashful country star draws added strength to his already ridiculously powerful voice.

“When you have nights when you don’t feel like you’ve got it in you vocally, you kind of look to [Morgane] and lean on her and it pulls something out in that,” says Chris. “She’s strength in a lot of ways. You know?”

Chris and Morgane have been married since 2007 and have welcomed two children to their family—with twins on the way.

“She knows all my tricks—that’s what I tell people—onstage and off,” says Chris. “It’s a cool thing. I don’t think I know anybody else who gets that level of, you know, being married, but also working and interacting, and sometimes that’s a hard thing to walk around ’cause we’re married, but also, how cool, you know? And, we take the kids out and we’ve got just a traveling family road show. It’s fantastic.”
