Jessie James Decker is enjoying Christmas with her family of five — before it expands again!

The pregnant country-pop singer, 35, who is expecting baby no. 4, celebrated the holiday with husband Eric Decker, 36, and their three kids — sons Forrest Bradley, 5, and Eric "Bubby" Jr., 8, along with daughter Vivianne Rose, 9 — by posting a series of photos on her Instagram.

In a sweet photo, Jessie and her three kids wear matching Christmas pajamas, with the musician's shirt rolled up to expose her belly. All three kids plant a kiss on her stomach, with Jessie smiling for the camera.

The mom of three also included a photo with her whole family, 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.

"🎄Last Christmas as a family of 5 until baby brother is here❤️ We love you already sweet boy💙🎁🎄✨Merry Christmas Eve y’all🎄" Jessie captioned her post.

While speaking to PEOPLE in October, the musician opened up about welcoming her fourth baby with Eric. "Pregnancy, for me, is easy, but I would say this has been the easiest of all of them," she revealed. "I can't complain."

"I always laugh and say like Vivi tried to kill me in the beginning. It was the roughest pregnancy I've ever experienced in my life. My middle child [Eric] was fairly easy. Forrest was also pretty rough on me, which is really funny because I would say Vivianne and Forrest are probably the most alike. But this one's been fairly easy."

She also said the news of baby No. 4 "shocked" and surprised both the family and their loved ones.

"Eric didn't believe me at first. He thought that I was playing a joke on him," she laughed. "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."

"Every single day feels like Christmas. We just can't believe this is happening," the expectant mom raved. "We're such a tight little wolf pack. It's so exciting to bring another baby into our family."
