It’s no big secret that Jessica Simpson has been trying her hardest to shed the baby weight. Simpson delivered daughter Maxwell Drew Johnson back in May and instantly inked a $4 million deal with Weight Watchers to lose the weight. But it looks as though she’s finally found her niche in the Weight Watchers program because she filmed her first commercial!

“That’s a wrap! Just finished shooting my first @WeightWatchers commercial! Stay tuned…,” tweeted Simpson to her followers. Simpson, who has been following Weight Watchers’ diet plans religiously, has also been working out with Hollywood trainer to the stars Harley Pasternak. “Jessica is so excited to show off her hard work,” a source close to the 30-year-old said to RadarOnline. “She’s finally dropping some weight and she’s so happy to be getting back into shape.”
