Chris Stapleton‘s got his best gal by his side for support — and his baby on the way.

Walking the red carpet together at Sunday evening’s Grammy Awards in Los Angeles, the “Millionaire” singer and his wife Morgane posed for photos while the latter showed off her baby bump under a long billowing blue dress.

The fifth-time mama-to-be — who is pregnant at the Grammys for the second year in a row! — pulled the look together with sandals and a black clutch, wearing her blonde hair in loose waves. Stapleton, 40, kept it simple yet debonair in a black suit, black shoes and a cowboy hat.

Speaking exclusively to PEOPLE on the red carpet, the couple said they’re due in the spring while Morgane said she’s taking bathroom breaks “every 30 minutes, if I’m hydrated. It’s gonna be a lot tonight.”

Stapleton is up for three awards: best pop duo/group performance, best country solo performance and best country album for From a Room: Volume 2. He has won five Grammys in the past — and 2019 victories in the latter two categories would mark his second year running of winning them.

Just seven months after the couple welcomed twin boys, the father of four announced in November that he and his wife, 36, are expecting their fifth child, during a concert at Madison Square Garden in New York City.

“Some of you may know that we have four children,” the musician said, according to a video published by The Blast. “We just had twins, about seven months ago. Now there’s four for us, but we’re gonna make it five!”

Chris and Morgane, who wed in 2007, are already parents to three sons (including their twins) and one daughter but have chosen not to publicly reveal their names.

That wasn’t the first time Stapleton announced baby news during a concert. Last year, the “Broken Halos” crooner shared that he and his wife were expecting twins during a performance in Dallas at Starplex Pavillion.

“She’s the mother of my two kids, and she’s about to be the mother of two more,” he said.

After the boys were born in April, Stapleton gave Reba McEntire the honors of announcing their arrival when he won album of the year at the 53rd Academy of Country Music Awards, which he was unable to attend.
