Simpson-Wentz slams sister's critics

Ashlee Simpson-Wentz has defended her sister's curvy new look.

The singer and actress told US magazine Women's Health that Jessica looks "incredible".

Commenting on the negative press her sister has received for putting on weight, Simpson-Wentz said: "It's disgusting that people would say those things.

"My sister has an incredible body. I feel sorry for anyone who would judge her because she's one sexy lady."

The star, who is married to Fall Out Boy member Pete Wentz, went on to say that she is happy with her current slender physique.

However, she added that she is not worried about putting on a few pounds in the future.

"There's gonna be a time when I'm way curvier and that'll be sexy too," Simpson-Wentz stated.

The mum-of-one also revealed that her husband's attitude makes it easy for her to accept the way she looks.

"Pete isn't worried about stretch marks. He always makes me feel good," she explained.
