Jessica Simpson sympathised with Kim Kardashian after she was criticised for her pregnancy weight.
The reality TV star gave birth to North ? her first daughter with partner Kanye West ? in June, and the Fashion Star mentor has defended her after she got mocked for her own curves.
Jessica ? who also has a daughter, Maxwell (15 months) ? told Us Weekly, "I felt for Kim; I knew exactly what she was going through . . . I send a lot of love her way, and I know she'll come back with a bang."
The 33-year-old singer doesn't "understand" why women are given a "hard time" when they gain weight during their pregnancy.
She added, "I will never understand why people give pregnant women such a hard time.
"We are creating a human life: I think we get every excuse in the world to eat a doughnut!"
Jessica also praised Britain's Duchess Catherine for "glowing" while she was waiting to give birth to Prince George ? and admitted she doesn't mind that she "can't help" gaining weight.
She said, "Kate Middleton was glowing throughout her pregnancy. A lot of pregnant moms were looking at her, like, 'How do you do that?'
"I am definitely one of those pregnant women who just gains a lot of weight. I have really big boobs, I have my curves and I just gain weight.
"I can't help it . . . It's been six weeks since I've had my baby [son] now, and I feel great . . . It's okay to gain weight, and it will always come off."
