Jessica Simpson has been trying to lose the 70 pounds she gained while pregnant with Maxwell Drew, and perhaps nobody understands her struggle better than fellow reality star Kendra Wilkinson.

"That just breaks my heart," Wilkinson, 27, tells Yahoo! OMG. "I feel for her. I was in the same boat. People just need to mind their own business. That's a woman who just gave birth."

Though Simpson, 32, has plenty of initiative to slim down -- thanks to a $4 million contract with Weight Watchers -- Wilkinson hopes critics will stop scrutinizing the Fashion Star mentor's figure.

"Her first priority right now is her child. Her first priority is not losing the weight. You should be proud of her for that," the WE tv reality star says. "A lot of people just dump their kids off at nannies and lose the weight overnight. We should all be proud of her for being real and taking control and making priorities."

Simpson, for her part, is taking it one day at a time. "The cool thing about the [Weight Watchers] 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 explained via Facebook in May. "I have actually gotten a group of friends together who are going to be doing it with me."

The 5-foot-3 Texas native follows in the footsteps of previous Weight Watchers spokeswomen Jennifer Hudson, 30, Jenny McCarthy, 39, and Sarah Ferguson, Duchess of York, 52.

"We're thrilled that Jessica Simpson has chosen to join Weight Watchers to adopt a healthier lifestyle and inspire others to do the same," the company said in a statement. "Her talent, resilience and positive outlook already make her a great role model, and by deciding to trade in yo-yo dieting for a healthier lifestyle, we know she will inspire many women to join her."
