Nobody has ever called Jessica Simpson stupid, at least when it comes to her business acumen. The new mom will get a hefty paycheck for her efforts in battling the post-baby bulge. The serial yo-yo dieter just signed on to be a Weight Watchers spokesperson for a whopping $3 million. Of course, that's likely chump change for the singer-actress whose beauty and fashion lines brought in an estimated $1 billion last year. Of course, the 31-year-old has plenty of incentive to make the Weight Watchers deal pay off. For starters, the buxom blonde received a great deal of flack for her weight gain during pregnancy. And with an impending wedding, Simpson will definitely be motivated to shed the baby weight for the big day. Simpson gave birth to Maxwell Drew Johnson on May 1. Her daughter weighed in at 9 pounds, 13 ounces.
