The Eric & Jessie: Game On stars welcomed their third child together, a baby boy, on Saturday.
"Forrest Bradley Decker born March 31st weighing 9lbs. We are so in love," Jessie captioned a photo with her newborn on Tuesday.
The country singer and the NFL star announced they had another child on the way in October 2017, and later that month, they revealed they were expecting a son.
At the time of the gender reveal, Jessie posted an Instagram video of her two other children, Vivianne Rose, 4 and Eric Jr., 2, opening a box filled with blue balloons.
Jessie told Us Weekly late last year that her husband was the one who wanted to expand their family.
"[Eric] wanted it. He's the one that was pushing this. He's very excited, he's always wanted a big family," Jessie previously told the magazine.
"He loves me pregnant. It's one of his favorite times. He told me, 'I just love you pregnant. It's just my favorite. I love your belly. I love everything about it.' And I cook a lot, but when I'm pregnant, I cook even more and I experiment with more foods and stuff, so he loves that."
Jessie shared her pregnancy journey with fans, documenting her baby bump and progress on social media over the last several months.
At 36 weeks, Jessie shared a picture and opened up about how difficult things were for her physically.
"[I'm] beyond uncomfortable! This baby feels so low and my bladder has about had enough! Ha! Sleeping is just not even a thing anymore lol It is bittersweet though since this is my last pregnancy and it is a beautiful thing," Jessie wrote on March 11.
"I know I will miss this feeling one day and miss my baby roll around and kick and the sweet little hiccups. I love a lot of things I do in this life but nothing compares to how much I love being a mommy. #babynumber3#36weeks #almostthere."
Eric and Jessie got married in June 2013. Their daughter Vivianne was born in March 2014, and then they welcomed Eric II in September 2015.
The third season of the couple's reality show, Eric & Jessie: Game On, wrapped in late October 2017.
