Jessica Simpson has been hard at work to lose all that baby weight she padded on while pregnant with her daughter. Simpson showed off her new skinny bod in Florida while promoting her clothing line at a Dillard’s in Tampa, FL.

The new mama tweeted out a picture of herself at her Weight Watchers commercial last week. She’s lost almost 60 pounds since giving birth to her baby girl, Maxwell Drew, back on May 1st.

Jessica is definitely looking fabulous and fantastically fit! We can’t wait to see her new Weight Watchers commercial!
