Why Pregnant Jessie James Decker Is "Definitely Done" Having Kids After Baby No. 4

Jessie James Decker admittedly was tempting fate by making a whole commercial about husband Eric Decker not getting around to that vasectomy yet.

It was a campaign for Ryan Reynolds' Aviation Gin in which Jessie prepared a cocktail named after the procedure—"So easy," she deemed the, er, recipe—but little did the singer know that fate would have the last laugh.

"We weren't pregnant yet," Jessie told E! News in an exclusive interview, referring to when they shot the ad earlier this year. "Ryan was telling us about how [he and Blake Lively] had just had another baby. And the boys were laughing about how Eric hadn't gotten a vasectomy yet, and I'm just kind of sitting there, like, 'I don't know...'"

She added, "It's funny to think that just a few weeks after that I was going to be getting pregnant."

They found out they were expecting baby No. 4 not long before their 10th wedding anniversary on June 22, Jessie recalled. And while she and Eric had been planning a romantic adults-only getaway to Mexico to celebrate, the mom of daughter Vivianne, 9, and sons Eric Jr., 8, and Forrest, 5,continued, "I was just so emotional and excited and feeling the family love, I was like, 'Let's just switch gears and take the kids with us.'"

So, they booked a whole different vacation and "it was really special to spend it with the babies," Jessie said, "because we have another baby on the way and it's such a family affair for us."

And while she said "the fourth was a surprise," the 35-year-old had this feeling that their kids were going to get another sibling one of these days.

"We could not be more excited about it," Jessie continued. "Even though I was set with three, I'm a very intuitive person and just have that thing."

But once the new baby arrives, the family will then be complete as far as she's concerned.

"We're done," Jessie said. "We're definitely not going for a fifth." While she "always knew" they would have a fourth, she added, "I don't see five in the cards at all. I always felt a fourth, so it makes sense."

And however many are sitting at their table, in chairs low or high, the author of Just Eat: More Than 100 Easy and Delicious Recipes That Taste Just Like Home always has food for a small army on hand.

"My whole thing on cooking is, let's just get to it," Jessie explained of her latest accessible repertoire of recipes, which is a follow-up to her first cookbook, Just Feed Me. "I am not a chef, I never pretend to be, I am a home cook, and everything I've done has either been taught by my mother, grandmother or has been self-taught."

While the yumfest—and we don't just mean Eric's NSWF promo pic—includes everything from Monkey Bread in all its sugary gooey glory to a lobster risotto she whipped up at a friend's house with a limited larder ("It was like a scene out of a Chopped episode)," Jessie also made sure her kids were represented in the otherwise family-friendly release.

Forrest wants pasta every day, she shared, while Eric Jr. is "a salad guy—I know, he's 8 years old." And Vivianne, "a very serious gymnast," according to Jessie, added her favorite strawberry smoothie recipe to the mix.

As for her husband redefining the concept of hard sell tactics, Jessie said of course it was her idea for Eric to strip in service of getting the word out about Just Eat.

"He's so gorgeous," she explained of the 36-year-old retired football player, and "so chill, too. He's just easygoing. He's not fazed by a lot, he doesn't care. So he goes along sometimes with my silly little ideas, where he just laughs and, I'm like, 'Hold the book!'"

Let's just say, delicious is a word that doesn't always need to pertain to food in the Decker household.

Yet that being said, the kitchen obviously sees a lot of action year-round. And as cozy season gets underway, Jessie is looking ahead to the holidays and all the eating that entails. They'll probably be going to another family member's house for Thanksgiving, Jessie said, but then she likes to go all out for Christmas, whipping up a dozen courses on her own.

"I get so excited," she gushed. "It's my favorite time of year. And especially now, I can nest and hibernate and eat and just prepare."

While Jessie was starting to "feel kicks and rolls," she noted, the baby wasn't yet fist-bumping the outside world. Still, the kids were "all trying to put their hands on, like, 'Is the baby moving yet?'" the singer shared. "It's been really sweet."

They do know the sex of baby No. 4 and picked out a name, she revealed: "Everyone's happy, we all agreed on it, so we're rockin' and rollin'." 

But while it made sense to get familial consensus as far as naming this new human being was concerned, Jessie has long since concluded that it's only the opinions coming from inside the house that matter.

"We're so normal and our kids are so healthy and happy and amazing, it would be silly for me to ever get upset about anything," she said of disregarding the parenting critics (i.e. complete strangers) who tend to swarm around famous moms online. "We're doing good, so I'm not worried about it."

Besides, she added, "people are always going to talk—that's social media. And I got too much going on to think about it or worry about it. I got babies to look after."

Just Eat is on sale Oct. 10.

The Decker's youngest, Forrest Decker, turned one in March of 2019 and of course they celebrated with balloons and kisses!

"Loves of my life #feelingrateful," Jessie James Decker captioned this sweet photo of her kids and her husband Eric Decker.

The Deckers visited Disneyland in February and despite trying to be romantic, the couple was photo-bombed by their son Eric Decker II. 

In January, the Decker boys cuddled up on the couch...dressed in their Woody pjs and watched some football.

On Christmas Eve, the Decker kids got into a little mischief, but we still think they're cute.

Come on, could these two be any cuter?

All three of the Decker kids including daughter Vivianne Decker, and sons Eric and Forrest were all smiles while out at the grocery store in November 2018.

We are loving all of these adorable costumes from Halloween 2018.

"My whole purpose in life #mifamilia," Jessie captioned this vacation snap from 2018.

What better way to celebrate 4th of July than hanging out on a boat with your sweet family?

Not everyone was happy to take this photo, but that didn't stop mom and dad from posting it.

In June, Eric became a human jungle gym thanks to his little kiddos.

Vivianne clearly loves her little brother Forrest in this precious pic from April 2018.

The former football player is always ready to hug it out with his little munchkins. 

Even though Jessie was sick in this photo, she had her two oldest kids to keep her spirits high.

In December 2017, the two oldest Decker kids had a big smile when they met Santa. 

Getting ready for Halloween is so much more fun when someone is wearing a Mickey Mouse head!

Aw, our hearts are so full looking at these two.

The country singer looked adorable as she waited to watch her husband's first game as a Tennessee Titan with her kids in August 2017.

The award for most patriotic family has to go to the Deckers.

Kisses and cuddles are what these two are best at and it's so freaking cute.

Vivianne got up on her dad's shoulders as the couple participated in a charity event in Tennessee in 2017.

"My wolf pack!" Jessie wrote alongside this photo of her family of four back in March 2017.

This party looks like a blast and we officially want to be invited to the next one.

Before the Deckers were a family of five they were hitting up weddings as a squad of four and looking good while doing it.

For Halloween in 2016, the fun family dressed up as characters from Peter Pan and they totally nailed it.

Ahead of Eric's 2016 season with the New York Jets, his family joined him at practice and we got this sweet photo as a souvenir. 

There's nothing quite like a family day at Disneyland.

Back in November 2015, the super mom and her two little ones enjoyed watching their main man dominate on the football field.

For Halloween in 2015, these two kids dressed as the princess and her frog and we don't have words!
