Jessie James Decker is due in early 2024 with her fourth baby—but it's not stopping her from rocking a bikini.

On Monday, Oct. 23, the country music singer took to Instagram to share bump photos with her 4.3 million followers. Decker referenced a social media trend in which fans post pictures of their children and partners while playing a song of hers released in September.

"Love seeing how y’all are using 'I’m Gonna Love You' in your own posts with your precious families??," she wrote. "I can’t wait to meet this sweet baby ?? Swipe to the end for now ????????."

In the carousel of photos, Decker shows a bump photo when she was pregnant with each of her children, followed by a snap of each child today. (She and retired NFL player Eric Decker share a daughter, Vivianne, and two sons, Eric "Bubby" Jr. and Forrest.) The last shot shows her pregnant with baby No. 4 and wearing a black bikini while posing with her hands on her bump.

Although Decker looked stunning in her two-piece swimsuit, the comments didn't focus as much on what she was wearing as they did about the sex of her unborn child.

One person wrote, "Belly looks like you're carrying like you did for your boys!"

"I'm guessing a girlie!" another follower commented.

Meanwhile, someone else begged, "Jess you gotta give us the gender reveal!"

Although Decker has not publicly shared whether her fourth child is a boy or a girl, the soon-to-be mom of four revealed she and her husband already know the sex. They also have a name picked out.

"We chose the name as soon as we knew the gender. We're always kind of prepared," Decker told People for an article published on Oct. 10. "I knew all my babies' names before they were born. It just comes to me instantly and we all are obsessed with the name."

Daughter or son, one thing's for sure: Decker's bikini bump game is second to none!
