This married lady is a skinny minnie!

Jessica Simpson and husband Eric Johnson have already returned from their Mexican honeymoon, but the fashion mogul must have been reminiscing because she decided to share some more pics from their vacay on her Instagram account.

In one snap, the blonde beauty posed with her hand on her hip in their hotel room in a floral maxi dress, and we've never seen her waist look so tiny!

In another photo, the couple looked lovingly into the camera and the mother-of-two captioned it, "I love this man, our marriage, and everything in between." The pair also showed off their silly side by sticking their tongues out at what looks to be the hotel restaurant.

Maybe we're naive, but we think these two will last!
