David Nail is on fire — on all fronts!

In addition to his hot new single, “Night’s on Fire,” the country singer is also set to become a first-time father — to twins!

Nail walked the red carpet at Wednesday’s CMA Awards with his leading lady, wife Catherine, on his arm.

And while the couple stunned in their evening ensembles — Nail in his dapper Zegna suit and the mom-to-be in a fuchsia dress — all eyes were on Catherine’s budding baby belly.

Nail told PEOPLE they’re expecting both a boy and a girl and that she could give birth “any minute now but hopefully in the next four weeks.”

“We struggled with infertility for years and really just had to stick together to get through it,” Catherine said.

Her husband added, “Everyone tells us instincts take over and that’s what we’re hoping.”

The news is yet another bright spot for Nail, who spent 10 years living in deep depression before “bottoming out” in 2012.

“I carried around a lot of guilt because I had all these blessings in my life and yet I was still struggling to try to find some joy,” he told PEOPLE in April 2014.

Nail — who’s currently out on the Southern Style Tour with Darius Rucker — and Catherine wed in 2009.
