It's no secret the 35-year-old fashion entrepreneur couldn't be more in love with her husband, former NFL player Eric Johnson, and she made sure to remind her two million Instagram followers on Wednesday.
"Happy to procreate with this Man," Simpson hilariously wrote alongside a glamorous black-and-white photo of the two leaving John F. Kennedy airport in New York City.
The mother-of-two looks skinnier than ever in the shot, sporting black trousers and a fitted black sweater with white bell sleeves. When ET caught up with Simpson at the YMA Fashion Scholarship Fund Awards Gala on Wednesday -- where she was honored with the Future of Fashion Award -- she said that she's been able to keep the weight off just by being a mother to her two children, 3-year-old Maxwell Drew and 2-year-old Ace Knute.
"I think being a mom is enough of a diet," Simpson said. "You have to run around chasing your kids, but I do eat a lot of their corn dogs, so I have to get on the treadmill a lot to watch my TV shows."
Simpson echoed those sentiments when we caught up with her in September at the 10th anniversary celebration of the Jessica Simpson Collection at New York City’s Tavern on the Green.
"A lot of squats! A lot of push-ups, got to keep these things up," she said when asked about her workout secrets. "And running around with my kids. That is a diet in itself."
Although Simpson also told us back in September that she had no more plans to expand her family, judging by her latest Instagram, is the singer now ready to have more children with Johnson?
Not so fast.
"Oh good Lord, I don't think I could have another baby right now," she admitted to ET last week. "It was a very, very big shock after having a baby and four months later, knowing I was pregnant again. So I think that's not in our near future."
