Jessica's journey from chubby to hottie

   Simpson subsequently signed up as the new spokesmodel for diet plan WeightWatchers and has since lost 40 pounds (18 kilograms).
    Jessica Simpson recently revealed her post baby body on the premiere of Katie Couric's talk show, asserting that shedding off those extra pounds were 'challenging.'
  

  The actress disclosed that she lost 40 pounds since the birth of her daughter, Maxwell Drew Johnson in May. "During pregnancy, I didn't really think about it," ABC news quoted Simpson as telling Couric.
  

  The singer and actress recently admitted to piling on the pounds while pregnant with her baby daughter Maxwell because she wanted to enjoy her first pregnancy.
  

  "I thought my doctors were telling me that it was just a lot of water and whenever my water broke my whole entire stomach would go down but that did not happen. All the weight did not come out with the baby," she added.
  

  The 32-year-old, who weighed 170 pounds when she posed nude and pregnant for the April issue of Elle magazine, had signed a reported 3million-dollar contract, earlier this year, to be the celebrity face of Weight Watchers.

     Simpson explained that she is still 10 pounds away from her goal weight, which she will cover using her daughter.
   

  "I basically take her with me, whether it's strapping her on me or strolling around the neighborhood. My new goal is 14,000 steps a day."

Jessica Simpson has reportedly dropped 60-pounds of baby weight in four months - thanks to her extreme four-month crash diet plan that features low-fat smoothies, protein and plenty of vegetables.

According to TMZ.com, the 15-day smoothie diet consisted of five days of three smoothies a day that gradually worked in snacks and meals, the New York Post reported.

The plan followed the basic Weight Watchers point system and included foods like egg white omelets, chicken, chick peas, and shrimp skewers.

Simpson's initial attempt at weight loss was ridiculed by some. She drew criticism for her September Weight Watchers commercial because it only featured her face and it appeared as if she wasn't dropping pounds quickly enough.

jessica Simpson is reportedly pregnant with her second child, just seven months after giving birth to her first daughter Maxwell.

"It definitely wasn't planned. But yes, Jessica is pregnant again," the Mirror quoted a source as telling Us magazine.
