Simpson has famously been struggling to lose the 40 to 50 pounds she gained in pregnancy, especially since Weight Watchers offered her a rumored $4 million deal to lose the weight by a certain date.
Dressed in a fitted black outfit, Simpson tweeted a picture of her on set, looking surprisingly slim. It is likely that Simpson will be revealing her whole body in this new Weight Watchers commercial, as in her first one, there were only shots of her face.
In September, Simpson first showed off her weight loss while on Couric's new show, "Katie.” Simpson talked with Couric about her weight struggles, stating, "I thought my doctors were telling me that it was just a lot of water and whenever my water broke my whole entire stomach would go down, but that did not happen. All the weight did not come out with the baby."
But Simpson says that though she has a lot of pressure on her to lose the weight, she is not in any rush.
"I've just had a lot of pressure on me and today was actually one of my goals," Simpson told Couric.
Former Playboy Playmate Kendra Wilkinson, who also struggled to lose weight after giving birth, came to Simpson's defense, saying, "That's a woman who just gave birth. Her first priority right now is her child. Her first priority is not losing the weight. You should be proud of her for that. A lot of people just dump their kids off at nannies and lose the weight overnight. We should all be proud of her for being real and taking control and making priorities."
