Earlier this month, Morris performed at the Houston Rodeo while 9 months pregnant.
Morris made the pregnancy announcement on Instagram back in October, sharing a maternity photo.
"The irony is just too rich that after a year of living in the "GIRL" headspace, the universe would give us a baby boy to even things out," Morris wrote. "See you in 2020, little one. 👶🏻"
Hurd also shared the news on social media."Look at her...can't believe it," Hurd wrote. "See you in March, baby!"

In 2019, Morris told People that she and Hurd were excited to start a family.
"If you're gonna get married, you have to have those talks beforehand anyways, and I definitely know that I want a family, and he would be such an amazing dad; he's such a kid himself," Morris told People. "I love his family, and he loves my family, so we've definitely had those conversations, and they've been really fun and exciting."
