Jessica Simpson Loses More Weight: Mom Shows Off Post-Baby Body In New Interview [PHOTO]

Jessica Simpson is looking more svelte than ever, nearly seven months after giving birth to her son Ace. The entertainer-entrepreneur showed off a slimmer body while on Good Morning America Tuesday morning. Wearing a form-fitting black sleeveless dress with nude panels, the 33-year-old showed that Weight Watchers is working wonders for her figure.

“As a mom I just have this confidence and I just feel so proud of what I’ve done and what I’ve accomplished. And I really do also feel this need to just be the best role model for my children and I want Maxwell to look up to me and want to be like me. I don’t want to give her any false perception of what is real and what’s important.” Maxwell is her first child with fiancé Eric Johnson.

Last year, Simpson famously struggled to lose the reported 70 pounds she gained in her first pregnancy. There was a lot of pressure on her, especially since Weight Watchers offered her a rumored $4 million deal to lose the weight by a certain date.

It took her many months to lose the weight -- and then she got pregnant again. This time around, however, she hired a personal chef to help her keep her weight on track. “When I was pregnant with Ace, my second, I had already been on Weight Watchers and I had already lost over 50lbs and so I wasn’t as relaxed in my eating and everything that I was with Maxwell,” she explained on GMA.

“But I was just already in a healthier regiment so I kept walking and staying active and Maxwell started walking. It’s a lifestyle and I’ve tried so many different diets and you can only stick to something for so long.”
