The mother-of-two also snapped a photo of her children, Maxwell, and son Ace on Wednesday which she posted on Jessica Simpson Instagram. She captioned the post, "There is no way these kids could be more adorable. OMG! So happy to be home snuggling!" 

In an interview with People, Jessica Simpson said that it was "overwhelming" to be the wife of Eric Johnson.

"It was amazing to feel the love of everybody and to be able to have our babies and watch us say 'I do.' It's a moment you can't describe," the Texan native said.

Meanwhile, Jessica Simpson's former husband Nick Lachey is now happy with his new wife Vanessa Minnillo. The couple is expecting their first baby girl, their second child together.
