She said: ''That just breaks my heart. 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.''
The 32-year-old 'Fashion Star' mentor signed a $4 million contract with Weight Watchers in an attempt to lose weight after giving birth to daughter Maxwell Drew on May 1.
Kendra told website Yahoo! OMG: ''Her first priority right now is her child. Her first priority is not losing the weight. You should be proud of her for that.
''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.''
Jessica recently said: ''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). I have actually gotten a group of friends together who are going to be doing it with me.''
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.''
