Jessica Simpson has revealed that she was envious of Duchess of Cambridge's pregnancy and empathised with Kim Kardashian's.
The 33-year-old music artist said that she felt for the 32-year-old reality TV star as she knew what exactly Kardashian was going through, Us magazine reported.
Simpson, who was often ridiculed for her own growing curves when she was pregnant with daughter Maxwell, said that she would never understand why people give pregnant women such hard time on gaining weight.
The 'Sweetest Sin' hitmaker said that Middleton was glowing throughout her pregnancy and she wondered how the Duchess did that.
Simpson added that she is one of those women, who just gains a lot of weight.
