Chris shared the news with fans during a show on Oct. 28 in Dallas. And on Monday night -- the couple's 10 year anniversary -- Morgane shared the news through a caption in an Instagram post.
"14 years, 2 babies, & 2 more on the way," wrote Morgane.
The Stapletons have one of the sweetest marriages in country music. The couple met over a decade ago while working as songwriters at a publishing house in Nashville, and married in 2007. Chris had his ring engraved with "You Are My Sunshine," a song which the pair has long performed as part of their live show.
Career-wise, the coming year is shaping up to be a big one for the Stapletons. On Dec. 2, Chris drops From A Room: Volume 2, the follow-up to his widely acclaimed sophomore album.
The Stapletons performed "Broken Halos" together during the 2017 CMA Awards. The song was a partial tribute to the victims of the Las Vegas shooting. They were also remembered by Carrie Underwood, who performed a moving hymn while images of the victims were shown. Chris walked away with the award for Male Vocalist of the Year, and the couple happily showed off Morgane's baby bump while on the red carpet.
2017 has also been a big year for baby announcements in the country music world. Thomas Rhett, Josh Abbott, Justin Moore and Lee Brice are among the handful of country stars to welcome new additions to their families this year.
