Jessica Simpson Back on Weight Watchers

Jessica Simpson is officially a Weight Watchers spokesmodel again!

Simpson first signed up with Weight Watchers after gaining 70 pounds while pregnant with her daughter Maxwell, but had to quit after she got pregnant with her second child, Ace Knute, just seven months after giving birth. But now, Weight Watchers has just revealed that they've been working with Simpson since August.

Simpson gave birth to baby Ace on June 30.

"We were thrilled to welcome Jessica back on the Weight Watchers program in August," the company tells ET in a statement. "With a toddler on the run and an infant to look after, we know she needs a plan that's simple and fits into her life along with the support that's so important to moms with young children."

Simpson praised the program, which Jennifer Hudson also famously endorses, when she first announced their partnership last May.

"The cool thing about the program is that it focuses on healthy habits for the long-term (and I can still indulge in my guilty pleasures every now and then too)," she said.
