Transformation Tuesday: Jessica Simpson's One Smoking Hot Mama

It’s Transformation Tuesday, and this week we’re spot lighting the incredible Jessica Simpson.

The blonde bombshell has gone from a late 90’s pop star to a fashion mogul with a company worth more than a billion dollars! ET recently saw the 33-year-old at the Forbes Women’s Summit in May where she revealed what has helped her in building her brand.

"I have been every size on the planet and I feel like I understand women," she told Steve Forbes and the audience at the event.

Jessica has maintained her candid demeanor for years, and has never been shy about sharing her dieting struggles with the world.

"I had a moment there when I was standing on the scale and faced with a severe truth,” she admitted in a Weight Watchers I’m Only Human And Did It  video about what happened when she looked at the scale for the first time a month after giving birth to her daughter Maxwell in 2012. “I didn't know if I could do it. I really didn't know that it was going to happen for me."

But, the mother-of-two has also never been shy about showing off the long hours she puts in at the gym. The singer spent two hours a day, six days a week in the weight room doing squats, lunges, and cardio to fit into those famous denim daisy dukes for the 2005 film The Dukes Of Hazzard.
