Pregnant Jessie James Decker Shares Baby Bump Beach Photos with Husband Eric Decker: 'Big Belly, Big Baby'

The country-pop singer is expecting her fourth baby — another son — in the new year

Jessie James Decker is spending the end of the year with her bump out on the beach.

On Thursday, the pregnant singer, 35, shared two Instagram photos from a sunny day by the water alongside her husband Eric Decker, 36. Jessie — who is expecting a baby boy — bared her growing belly in a white bikini while her husband stayed warm in a half zip sweatshirt over his shorts.

“Big daddy, big t---ies , big belly, big baby,” Jessie captioned her sweet pictures with the retired NFL pro. In the background of one slide, their 5-year-old son Forrest Bradley can be seen playing in the sand.

The country star’s baby bump has been a central piece of her family’s festive holiday season. On Christmas Day, Jessie commemorated their “Last Christmas as a family of 5” on social media with several fun photos taken at home. In one shot, Forrest and his siblings Eric "Bubby" Jr., 8, and Vivianne Rose, 9, all plant a kiss on their mom’s stomach.

The mom of three also included a photo with her whole brood, sitting in between her kids on the couch while Eric posed on the left. She added a few snaps of the family's Christmas Eve festivities, which featured milk and cookies, presents and stockings.

In October, Jessie spoke to PEOPLE about her smooth pregnancy journey with baby no. 4.

"Pregnancy, for me, is easy, but I would say this has been the easiest of all of them," she revealed while discussing her cookbook Just Eat. "I can't complain."

She also shared how her loved ones reacted to her pregnancy, which she revealed to the world with an Instagram post in August.

"Eric didn't believe me at first. He thought that I was playing a joke on him," she recalled. "He thought that I had my sister, who was pregnant at the time, pee on a stick. It was hilarious. Once everyone realized, 'This is not a joke,' everyone was super excited. And we still are."

And while the “I Still Love You” singer says all of her kids are "pretty equally excited” to welcome another sibling, she adds that her eldest is ready to take on more big sister duties.

“She's the oldest and she really knows and understands what's going on,” Jessie said of Vivianne. “She will be 10 in March, right after the baby is born. So she's completely aware and she's taking it even more seriously. She's got a very big role."
