Jessica Simpson's quest for a slim post-baby body has had some setbacks, and the Fashion Star beauty has admitted she's not a supermodel and will not drop the weight as quickly as other notable A-list Hollywood starlets, but she's sure going to try.

The Texas-born beauty, who has shed most of the 70 pounds she put on during her pregnancy, told Us magazine, "I feel positive about how I've done so far and really good about the goals I have set.

"I really have to separate myself from the world's expectations and really just be healthy with myself.

"I'm not a supermodel. My body is not bouncing back like a supermodel. I'm just your everyday woman."

Before she gave birth on May 1, Simpson said her goal was to lose weight as quickly as Jessica Alba did, who admitted to Lucky magazine:

"I have 1,200-calorie meals delivered. But I also work out, so basically I'm starving. It sucks."

Simpson, 32, previously admitted she "didn't think" about gaining the weight during her actual pregnancy.

"I just always thought that my doctors were telling me that it was just a lot of water and whenever my water broke, my whole stomach would go down," she told Katie Couric last month. "But that didn't happen."

She told the magazine she's had much support meeting weekly with a tight-knit group that includes her mother and friends, as they focus on weight loss, and the journey getting there.
