Lookin’ good! Jessie James Decker took to Instagram on Sunday, December 1, to show off her amazing body, along with her most comfy outfit, which is actually a whole mood.

“My feet cold but my pits be sweating outfit,” the 31-year-old wrote on her IG Story while rockin’ gray briefs, a black sports bra and UGGs. We can’t help but notice the singer’s toned body and it’s honestly hard to believe she’s a mom of three. The “Lights Down Low” crooner shares Vivianne, 5, Eric, 4, Forrest, 20 months — with her husband, Eric Decker, and it’s quite possible they may expand their brood.

“I feel really good and complete with three,” she exclusively told Life & Style in June. “I do know that Eric kind of teedertots between three and four. I feel like in a perfect world he would have a fourth but you know, we’re still having those discussions where I’m not a hundred percent sure where I land.”

However, she’s not totally against having more kids and that’s mainly because of her handsome beau. “I’m more on the side of like we’re good for now, but how can you … I can’t turn down having another baby with that man,” she added. “He’s such a good daddy.” How sweet!

Jessie and Eric have been together since 2011 and like any other couple, they have their ups and downs, but they’re doing better than ever these days. “I am more in love with him today than I was nine years ago when I met him,” she exclusively divulged to Life & Style in November.

She continued, “I’m crazy about him. I think what’s really important is when you meet that person you want to spend the rest of your life with to make sure that that spark is so incredible that it lasts for years and years and years to come. I think we just had such a great foundation to begin with and it’s just stronger than it’s ever been.” Can we say relationship goals?!

The pair work so well together, especially with parenting, which is why they have such a strong bond to begin with. “My husband is my partner. He is great. I’m able to do what I do because of him and vice versa,” she continued. “We both take turns when we have stuff going on.” Teamwork makes the dream work, right?
