And Jessica Simpson is no exception, still breastfeeding and quite plump with the baby weight, Jessica has been spotted hitting the gym in LA. And her main motivation? Well, a whopping $4 million dollars to slim down to 130 pounds using the Weight Watchers programme. Nothing like money to motivate Hollywood celebs to look fit and fabulous!
