Weight Watchers VP of Media Sales Andy Amill reveals their spokeswoman Jessica Simpson is getting back on their roster of celebrity endorsers. The 33-year-old recording artist and actress is ready to shed off the extra pounds she got from her most recent pregnancy after she gave birth last June to her new baby Ace Knute Johnson.

Simpson discontinued her diet plan during her second pregnancy but is keen on repeating her successful weight loss from her first pregnancy with daughter Maxwell Drew Johnson. Indeed, "Being healthy has become a part of who I am," proclaims the Weight Watchers brand ambassador in a new TV ad for the weight loss company.

It seems that the fashion mogul is well on her way to getting back her pre-pregnancy body, as she was spotted earlier this week already showing off her cleavage and slimmer figure in a sexy black outfit. The "Fashion Star" mentor enjoyed a night out with fiance Eric Johnson (II) and 16-month-old Maxwell at the Sagebrush Cantina in Calabasas, California.

Likewise, the popular TV personality flaunted her curves in a lacy little black dress for a 30-second TV commercial for Macy's. Her Jessica Simpson Collection of clothing, shoes, handbags, fragrances, jewelry and sunglasses are carried in department stores all throughout the U.S. It was the first celebrity brand to break the $1 billion sales mark as early as back in 2006.
