Jessica Simpson: Working hard to lose weight

Jessica Simpson is "working very hard" to lose weight.

The 'Fashion Star' mentor gave birth to her first daughter named Maxwell Drew on May 1 and signed a $4 million contract with weight-loss brand Weight Watchers to become a representative for them.

Now, even though she knows her image change will not be drastic, Jessica is excited about the expected transformation.

A friend told People.com about the star: "She understands it's a process. [She is] working very hard and she's excited."

After welcoming her child with Eric Johnson to the world, she said; "For me, I really want to do something that is a lifestyle. In the past I've been known to yo-yo diet."

The 31-year-old actress has instead been focused on losing weight gradually.

She has denied that there is a deadline for her to lose her post-baby weight and a representative for the company backed up her claim recently.

A spokesperson previously said: "Weight Watchers is in it for the long haul. We're with her 100 percent as she develops a whole new relationship with food and activity."
