Jessica Simpson Takes Her Baby Bump for a Workout

Jessica Simpson has vowed to be healthier for her second pregnancy, and it looks like she’s sticking to that promise.

On Wednesday, the “Fashion Star” judge hit a gym in Los Angeles in teal sweatpants, a black tank, black hoodie … and her growing baby bump. This is only one of a few times we have really seen her out and about during her second pregnancy, which she announced on Christmas Day with an adorable photo of her daughter with “Big Sis” written in the sand around her.

The following day, Simpson’s latest Weight Watchers commercial debuted, during which she admitted, "I lost over 50 pounds on Weight Watchers and did not have to be perfect to do it. Being healthy has become a part of who I am – which is great timing, because I'm having another baby.”

Although Simpson gained 70 pounds while pregnant with Maxwell, she realized soon after she gave birth on May 1 that while it may have been fun putting it all on, it was no picnic taking it all back off. During an appearance on “The Tonight Show With Jay Leno,” the 32-year-old admitted she had gained “a lot more than doctors would recommend” while carrying her first child. “I was really happy to be pregnant and I didn't ever step on the scale. I didn't realize you could gain that much weight that quickly."

But with the help of Weight Watchers (and a $4 million deal), Simpson went on to lose the majority of her pregnancy weight … before conceiving with fiancé Eric Johnson once again.

"I was extremely shocked," Simpson told Leno. "Because I was going through a lot of hormonal changes, trying to get back to the old, vibrant Jessica. You know, it was kind of like a one-night stand. And it happened, all over again!"

Except this time, it seems like she’s already getting a head start on maintaining her health.
