Weight Watchers should be proud! Jessica Simpson showed off her post-baby body at the 27th Annual Footwear News Achievement Awards in New York City last night (December 3).

With her two little ones — 19-month-old daughter Maxwell and nearly six-month-old son Ace — safely at home, Jessica took the event by storm in her Carolina Herrera floral print dress, black Casadei pumps, and Lorraine Schwartz jewelry.

During the evening, Jessica presented a Lifetime Achievement Award to her business partner, Vince Camuto. We think Jessica should have gotten a nod, too, just for the hard work she’s been putting in to shed the baby weight.

The design and music star credits lessons she’s learned as a Weight Watchers spokeswoman for helping her slim down in a healthy way. “An indulgence for me is like ice cream, so I can have a Skinny Cow for four points, and I know that that’ll be the sugar that I want that day,” she explained to ABC News back in October.

Jessica also says during her pregnancy with Ace she paid closer attention to what she was eating. “I didn’t limit myself, and I definitely was not on a diet during my pregnancy but I did stay active … I was a running pregnant woman.” And clearly that worked wonders!
