JESSICA SIMPSON

Jessica Simpson is struggling to lose 70-pound after she welcomed her second child, Ace Knute, in June. The singer is really disappointed with her post-baby body and she’s using Twitter as a way to communicate with her fans and help her to lose weight. She recently signed a four million dollar deal with Weight Watchers in order to lose the post-baby weight. Simpson must lose 20-30 pounds by the end of August, reported US Weekly.

"Responsibility has drastically changed my life! Saturday night drink of choice.... WATER! :) ," tweeted Jess.

The little boy is the brother of Jessica and Eric Johnson’s daughter, Maxwell.

'She says her stomach is 'goo', and she isn't sure if it's going to ever be like it used to be,' a source said. Jessica wants to regain her self-confidence after she gave birth to her second child, but she is also focused on being healthy for her kids .

"It's not about being [movie character] Daisy Duke. It is more about feeling good in her own skin, feeling happy about herself,' the insider explained. 'She wants to be able to run around with her kids without getting out of breath."

Jessica gained 70 pounds by eating snacks and cookie-brownie combo desserts. "Jess is talking about how she's eating vegetables and drinking green juice elixirs, but her shelves are still stocked with potato chips, frozen pizzas, and cookies," a friend of Jessica's told Star magazine.

The pressure is on, as the firm Weight Watchers is expecting to film some promos with the popstar in a few months.
